Need Help With Harness Wiring

[swag510]

Hey guys, I have an sr20 from s13. Im currently started to swap engine into datsun 510. I got most of wires marked up, but couple issues i run into are:
1. Lower harness by alternator and starter, what is necessary to connect? i seen couple plugs that are not connected. (i already connected power wire) So alternator wire and starter wire?

2. Relays for harness, i marked all wire relays. I should have 2 relays one for fuel and other for ecu power?

Any great suggestion on wiring relays, i currently have switches that operate everything. One is for ignition power and other for fuel pump (this is from my previous set up, build by previous owner)

Basically just trying to wire up ecu and fuel pump with aftermarket relays, if anyone has a DIY i will greatly appreciate.

Thanks guys

I know wiring specalities is making a kit for the 510 you could contact them and see.

I know for the lower trans harness ( on my 240 mind you) there were 3 or 4 necessary connections, starter, alternator, main power plug and i think 1 more.

Hey Morph
I wired up ecu with relays today, fuel pump and everything seem to work. I cant really tell till i replace my fuel line from fuel cell. I connected alternator and starter wiring today, starter clicks over. I still have to figure out rest of wiring on lower harness, to see what is important what can be just hidden.

I found this, it seems like exactly how my set up connected. So i will hopefully wire up fuel line and fire it up and see if battery charges.

Sweet, take some pics to document the progress and get a build thread going. Already sounds like its better than most on here.

i will do my best, wiring is mess though from previous owner having a metal dash . I had to trace every wire to see what it is because they are all RED
But if its starts up and i hope this weekend, then i can draw easy diagram for 510 owners and hopefully it will help.

Im in process figuring out how i will run return line, since i have a fuel cell and previous set up didnt have return line. And with single line that was running, he run it under suspension set up and rear arm cracked the line.

When more i get into this project then more ghetto crap i see, and im not any better with my wiring to the ecu but at least i labeled all wires with blue tape and made binder for wiring that ill keep with car

So i did wiring, and run fuel line today. I cranked over and it didnt fire up. So im testing at this point, i got spark and fuel but something holding it from cranking over. Timing was never moved from manufacture. Any ideas of what i might of missed? Next thing im going to check tomorrow if injectors getting power.

any suggestions will be greatly appreciated.
