Main Power

[jons14]

I recently purchased an abandoned project :picardfp:. It is a 89 s13 hatch, with a 7mgte with stand alone ecu (SDS ECU).

I am trying to finish up the battery relocation and provide power to the car to see if I can get headlights wipers etc to work. The stock ECU is in place along with the stand alone (not wired in yet). The stock battery cables have been removed and there are extension wires running out of the fuse/relay box located where the battery originally was. I tried grounding the fuse box and putting those wires +12v however nothing happened.

My question is, which wires inside the fuse box would I need to supply 12v power to, in order to power the vehicle.

Any and all help is appreciated!

Update:

WAS able to figure out which wires were the original + battery cables. Got the headlights/taillights/turns/hazard working, along with wipers, front and back, and rear defrost.

However the dash does not illuminate and the headlights do not flip up or down when the button is pushed.
