vetteguy22 Posted November 26, 2019 Report Share Posted November 26, 2019 I’m doing a complete rebuild of a 1971 Datsun 510 with a VG33, aftermarket gauges, electric power and heated seats, etc. i talked with painless wiring and they said they really couldn’t help me even with a universal kit. what have others done? Do I just start from scratch, one wire at a time or do I purchase a kit anyway and just completely modify it? any input would be helpful and appreciated. thanks, Rob Quote Link to comment
banzai510(hainz) Posted November 27, 2019 Report Share Posted November 27, 2019 If the original wiring is in the car still that would be best to start with.you can use the 510 wiring for all other stuff and use the 510 harness to trigger the VG motor harness.you get from the donor car. If you have no wiring what so ever then ask yourself how much ability you have to wire up the turn signals and emergency lights ect.... here where keeping the original is best.most jap cars are switchable ground and American is switchable power which confuses a lot of people. maybe best to sell the car if no wiring at all.just my opinion Quote Link to comment
vetteguy22 Posted November 27, 2019 Author Report Share Posted November 27, 2019 Thanks for your input banzai but the electrical is pretty close to the last thing I have on this project. The original wiring harness is not complete and has been cut and butchered pretty badly. i need to find a good alternative. Quote Link to comment
rosso Posted November 27, 2019 Report Share Posted November 27, 2019 Talk to icehouse - he posted a wiring article awhile back on here. Quote Link to comment
vetteguy22 Posted November 27, 2019 Author Report Share Posted November 27, 2019 Thanks rosso, ive seen that article and need to talk to him about a can/am box, but that’s only for the engine wiring. I’m hoping to rewire the complete car. Rob Quote Link to comment
banzai510(hainz) Posted November 27, 2019 Report Share Posted November 27, 2019 I don’t think Jeff has wire a whole car like turn signal stuff.He uses another 510 harness. Yeah He keeps the original car wiring for those items.He just makes a new harness for the new engine I think there is a company the makes harness for the engine management Wireing Specialties is the name Quote Link to comment
Jesse C. Posted November 27, 2019 Report Share Posted November 27, 2019 Just get and EZ Wiring kit, they are virtual copies of the Painless Wiring. I am using one in my 72 510 with a VG34 I have a VG34e, 200SX intake, 300ZX ECU and Harness, 240SX Throttle Body and the Can Am box. The rest of the car is the EZ Wire harness. I don't think anyone makes an aftermarket harness for this engine combo. SR, KA or something else, sure, but VG, no. You will have to re-use some of your plugs off the old harness to match your factory switches, but it can be done. Just get some wiring schematics and take your time. Quote Link to comment
demo243 Posted November 27, 2019 Report Share Posted November 27, 2019 Complete rewires can be done - done it in both my 510 and 620. Painless "can't" help you as all there stuff is ford/gm oriented... same as all the other wiring harness kits... but there are plenty of people who have used them. If you know anything about car electrical systems its not that bad a job, just takes some time and a little bit on ingenuity. I used the American Autowire Highway 15 kit for both of my rewires, but both cars are running pretty stripped down systems. Sounds like you are planning on running some additional items so it would probably be worth getting the 22 or similar kit so you have the spare fuses--- even if you don't use them as intended. You will have to re-use some of your plugs or you can get new ones from http://www.vintageconnections.com/ . Essentially you likely wont use any of the switches or connectors that come with the wiring kits. Although I did use the headlight switch on both cars and connected the lights with a bosche relay set up. Both jobs took me about 2 weekends to complete. I definitely recommend getting the CanAm box set up for the VG, made wiring in the KA in 620 super easy and keeps the engine wiring separate from the car harness. I'll dig up a couple photos of my two set ups Quote Link to comment
demo243 Posted November 27, 2019 Report Share Posted November 27, 2019 Here is the set up in my 510 - Hooked up all the relays under the glove box.

vetteguy22 Posted November 27, 2019 Author Report Share Posted November 27, 2019 Thanks for the input guys. I will definitely do my research today and decide what I need to do. Rob Quote Link to comment
vetteguy22 Posted November 27, 2019 Author Report Share Posted November 27, 2019 demo243, just curious if you used the factory key start switch or something else? Thanks, Rob Quote Link to comment

Thanks, Rob Yes used the factory Ignition switch on both. On the 510 I got the connection from Vintageconnections and connected it that way. On the 620 I just used female spade connectors on the ends of the wires. Quote Link to comment
