S15 sr20de swap now tach/tail lights don't work - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Just did an S15 sr20de swap in my s14. Engine runs perfect and drives perfect but my tail lights/brake lights don't come on and the tach doesn't work. My interior lights aren't working either but I don't know if that's related. Everything worked fine before the swap. The engine harness is custom and done by a very reliable person and I'm pretty sure that shouldn't affect the lights. I'm going to check all the fuses tomorrow morning but if that's not it I'm not sure what else it could be. Any ideas? Thanks

All my fuses are good. I'm thinking it may be wiring. Does the interior harness have to be modified from s15 to s14?

Checked the fender harness and relays. Everything is good. By the f3 plug is two white female connectors, anybody know if something is supposed to be plugged in there? I don't see any loose plugs near it.
