Like Wiring? Need help- will pay. Ka-t into 510

Trying to wire ka-t into datsun 510 that has rally-hacked wiring- will pay in food/beer/parts/reasonable cash for guidance and success- either by figuring out this wiring mess under the dash and in bay or starting from scratch. Looking for someone willing to come down too Waterdown for a friday or saturday or something- have apexi safc and various ka full and part harnesses- s13 ka24de engine harness/ecu is in car but far from plug and play.

So today we decided the “factory harness” was cluserfaked and we gutted the thing so yeah now i got a ka24de upper harness and a shell, so if your still down the plan is too wire it from scratch- ill pm you. I need help with relays, fuses, circuits and stuff.
