So I'm swapping my rb25 from my s13 to my s14.
I pulled the rb from my s13 and had no plugs in the firewall. Harness went straight to ecu and that is all. Nothing else. So I'm wondering if I can use the s13 harness in my s14 instead of forking over $400 on a new one when I could put that money elsewhere into the car since it was attached to nothing on the chassis, only the engine and ecu.
So basically, I'm just wondering what would be bypassed after putting the rb in my s14 and wiring it up. Everything worked perfect in my s13 except the speedo. Tac worked fine. All input is appreciated. Thanks guys.
