uberkevin Posted January 4, 2015 Report Share Posted January 4, 2015 Pretty sure there's a write up. Think it gives part numbers to some leds. And where he got them, Superbrightleds I think. I did this to mine. Super easy! 1 Quote Link to comment

DanielC Posted January 4, 2015 Report Share Posted January 4, 2015 I bought four of these lamps. The instrument cluster looked like this at night with stock lamps. It looks like this at night with the superbright leds installed 1 Quote Link to comment
a6m-zero Posted January 5, 2015 Author Report Share Posted January 5, 2015 Bam! http://community.ratsun.net/topic/16444-led-gauge-cluster/ Yup, that's the thread I used! Can you share more details of how you added led's in your clucter? or is there a write up somewhere? I've had dim ass lights in my truck since I got it and it would be nice if I could see my gauges!

DanielC Posted January 5, 2015 Report Share Posted January 5, 2015 This is the back of a 521 speedometer/gauge cluster. There are nine lamp holders on the gauge cluster, four black, and five grey. The black lamp holders are for gauge illumination. They just twist out counter clockwise, and the lamps are in the lamp holders. The lamp holders cam be two different types. One holds a bayonet base lamp, the other holds a wedge base lamp. Pull your lamp holders so you know the base type of lamp you need. You can reach up and get the lamp holders out without removing the gauge cluster. If any gauge lamps do not work, you may need to clean the lamp contacts on the gauge cluster printed circuit board. Use very fine sandpaper, or a Scotchbrite pad. The contact on the left side of one place for the lamp holder has been cleaned, the right side, not yet cleaned. If you need to remove the gauge cluster, this is how. Remove two screws at the bottom of the black plastic cover. The top of the cover is help with two spring clips, to disengage the clips, slide the plastic face straight up, do not pull it away from the dashboard. That will reveal two more screws, in brackets, at the top, that hold the instrument cluster. These screws have nuts, flat and lock washers on the backside of the dashboard. it is a little difficult yo reach them, and they are easy to drop. In most cases the dropped hardware stays caught inside the bottom lip of the dashboard. Sometimes they on the floor of the cab. With the screws out, there is a large black plastic plug that plugs on the multi pin connector on the gauge printed circuit board. Carefully work the plug off the circuit board. Pull the gauge cluster out slightly. you mak need to feed some slack in the speedometer cable into the cab, from the engine compartment. Unscrew the speedometer cable. Now you can take the instrument in to the house, where it is warm to work on it. 1 Quote Link to comment
wayno Posted January 5, 2015 Report Share Posted January 5, 2015 I have never seen the bulb holders mixed like that before Daniel, most the time they are all dark, and some are shorter, but usually they are all the same on any particular cluster. I don't hardly see the light gray ones, I only have a few of them. 1 Quote Link to comment

DanielC Posted January 5, 2015 Report Share Posted January 5, 2015 I have swapped combo meters around in most of my 521 trucks, and I have no way of knowing if any of them are like they came from the factory. On the other hand, I know there are two different lamps that look the same in a 521 combo meter. One lamp is about twice the wattage as the other. If my memory is correct, the four illumination lamps are the brighter lamps, and the lower wattage lamps are used for indicators. Two turn signal, oil light, Ign light, and high beam light. I could see an assembly line where one person puts higher watt lamps in grey lamp holders, and the lower watt lamps in the black lamp holders, and then the lampholders, with lamps, are put into a bin. The next person in the assembly line then knows which lamps go in the two different locations, without having to read very fine print on the base of the lamp, or testing each one. If you put the higher watt lamps in the two turn signal locations, it is easier to see the turn signal indicators in the daylight. 1 Quote Link to comment
wayno Posted January 5, 2015 Report Share Posted January 5, 2015 There are actually 5 different types of bulb holders that I have, in the photos below the 3 on the left are twist in bulbs, the housings on the 3 are all different in some way(color/shape), and the 2 on the right have the same shape, but one has a white dot on it, and the bulbs are the wedge type. 1 Quote Link to comment
blackdeth666 Posted January 6, 2015 Report Share Posted January 6, 2015 Thank you uberkevin, DanielC and Wayno for your help. This is for sure on my to-do list! Maybe i'll get a speedo cable at the same time since i'll have something to actually look at :devil: 1 Quote Link to comment

a6m-zero Posted January 14, 2015 Author Report Share Posted January 14, 2015 Well today did a little cleaning up. I stripped the horrible diy tint job someone did and the back window sticker that just wasn't my style. My lockes kept sticking so I lubed them up and now they work great......but I did make a boo boo. I noticed my passenger door was a little off from alignment to the door catch so I tried to adjust it a little. Well I mistakingly put my hand on the door handle as I was pulling up and broke it....(face palm). HELP ME! Let me know if someone has one in a box laying around! 1 Quote Link to comment

Z chopper Posted January 14, 2015 Report Share Posted January 14, 2015 somebody on here did a roll pan incorporating 620 tail lights. I'll see if I can find the thread. edit: found it http://community.ratsun.net/topic/1725-hackeds-521-turbo-bagged-right-hand-drive/page-18?p=640340&do=findComment&comment=640340 1 Quote Link to comment
a6m-zero Posted January 25, 2015 Author Report Share Posted January 25, 2015 So got in touch with Wayno and he sent me a handle to save the day! So big thanks to him! I have been doing a lot of wire chasing and fixing a bit of odds and ends. Got a lot figured out with the help of the Ratsun forums. Got my tail lights figured out and my roll pan is here waiting to be mounted! I'll be posting tomorrow some OICS cause I know that's all that wanted haha. I do have a lot of questions but I'll post them with photos! 2 Quote Link to comment
a6m-zero Posted January 26, 2015 Author Report Share Posted January 26, 2015 I'll start off with the fun stuff first. I ever since Got the truck home I have been frequenting local scrap yards and grabbing a few goodies. I didn't have a love box insert so I made one out of a Mazda B series one! The carnage! And in! I didn't have tailgate chains so I made those too! Also got my tail lights on! This is just the running. It's has it has Amber for the turns (which are scanning) and white for the reverse too! Now this is where I need the help of the wire gurus. These are all wire where I don't know what they go to or the function. Please help me out! I need to know if this is the factory full sender? Is this a factory mirror? Okay look forward to hearing responses! 2 Quote Link to comment
DanielC Posted January 26, 2015 Report Share Posted January 26, 2015 A mostly accurate 521 wiring diagram. The white wire, with a red strip. I amnot sure. When does it have power on it? All the time, or only with key on? what fuse powers it? Above left headlight bucket, Red wire, w/ blue stripe, female bullet connector, paired with black wire, male bullet connector, for left fender mounted side marker light. Two wires you are holding above the coil, some 521 trucks had a solenoid on the carburetor, that was used for parts of the emission controls. I think these two wires went to that solenoid. The single wire in your left hand, by the coil, what colors are on the wire? Red wire, by brake master cylinder. Might have gone to a switch, operated by the hood, that would turn on a small light above the starter, when the lights were on. The yellow wire, with a blue insulated spade connector, does not look stock, nor does the white plastic object in the same picture. Is that a different carb? The top of the gas tank looks stock. The yellow wire goes on the terminal by the fuel pickup hose. the black wire should go on a similar looking terminal close by. Not a stock mirrior. 1 Quote Link to comment
a6m-zero Posted January 26, 2015 Author Report Share Posted January 26, 2015 The white wire, with a red strip. I amnot sure. When does it have power on it? All the time, or only with key on? what fuse powers it? I'll have to trouble shoot this and get back Above left headlight bucket, Red wire, w/ blue stripe, female bullet connector, paired with black wire, male bullet connector, for left fender mounted side marker light. I have round side markers which are just reflectors correct? And these do not light up? Two wires you are holding above the coil, some 521 trucks had a solenoid on the carburetor, that was used for parts of the emission controls. I think these two wires went to that solenoid. So with the weber carb, these are not used then? The single wire in your left hand, by the coil, what colors are on the wire? This wire is coming off the coil, the lowest connection and it's a splice. You can barely see the splice in my hand. Red wire, by brake master cylinder. Might have gone to a switch, operated by the hood, that would turn on a small light above the starter, when the lights were on. I have that one hooked up so it has to be different, I'll look at the color. The yellow wire, with a blue insulated spade connector, does not look stock, nor does the white plastic object in the same picture. Is that a different carb? This wire is actually coming from the middle of that plastic peice on the carb. The top of the gas tank looks stock. The yellow wire goes on the terminal by the fuel pickup hose. the black wire should go on a similar looking terminal close by. I figured, maybe the black terminal was snapped off? I don't see it anywhere. 1 Quote Link to comment
denmarkboy Posted January 26, 2015 Report Share Posted January 26, 2015 I'll be posting tomorrow some OICS cause I know that's all that wanted haha.

Charlie69 Posted January 26, 2015 Report Share Posted January 26, 2015 If I am not mistaken you truck is actually a 1969 and it was first sold, titled and registered in 1970. The 1969 521 had the round reflectors not the side marker lights. Check the drivers door pillar for a date of manufacture. Quote Link to comment

a6m-zero Posted January 27, 2015 Author Report Share Posted January 27, 2015 So the stamp says 9/69. And daniel69, the first wire has constant power with no key. 1 Quote Link to comment
