realdiehl Posted September 21, 2012 Report Share Posted September 21, 2012 I have a 1970 510 and i have a bunch of wires in my engine bay that i have no idea where they go. I know it hard to tell in the pictures but i thought i would see if anyone had any ideas. . . . . . Quote Link to comment
datzenmike Posted September 21, 2012 Report Share Posted September 21, 2012 If these are Green/Yellow and Blue/Yellow they go to a carb switch that's part of the emissions system used in conjunction with the dual points in the dizzy to turn on or off the retard set. If there are 4 wires... Black, Blue/Yellow, Black/Red and Black/Yellow then this is the relay for the dual points. The Blue/Yellow wire goes to the above picture. I'm guessing you have an EI dizzy installed??? Probably a Weber too??? Some of the other wiring is likely for the ballast resistor and choke heater??? . Quote Link to comment
realdiehl Posted September 21, 2012 Author Report Share Posted September 21, 2012 Im guessing then that i wont need these wires anymore than. I didnt know if any of the wires power any of the non working gauges in the dash like the tachometer,temp gauge, heater blower Quote Link to comment
yenpit Posted October 3, 2012 Report Share Posted October 3, 2012 Do you have a wiring schematic for your 510? An OEM shop manual OR an aftermarket Haynes manual? If not, buy one! You can then trace the color-coded wires to the component (carb solenoid, dizzy, dual points, horns etc etc) in the pic. Anyone know if Paolo is still making the wiring schematic blowups? Those are great to have! BTW the carb solenoid wires will come out of the small sub-harness, right below the wiper motor. Do you have the original horns bolted to the chassis, either side of the radiator, behind the headlamps? Those loose wires on the drivers side could be horn (I can't see the color-codes)............

banzai510(hainz) Posted October 5, 2012 Report Share Posted October 5, 2012 alot of those wires whet to the point ignition and 3rd gear relay set up. also horn and window washer pump. and the yellow grn goes under the brake line block. another yellow clored wire goes to the temp. Should be ez to figure you. all you really need in that area is the blk /wht key ON wire. and maybe the HOT START blk blu wire to get this running. the rwst lets do one at a time. take photo and well show you.
