Hey guys,

So lets start with its a 1995 S14, automatic. I removed the KA24DE and the auto transmissions, with that being said the upper and lower harnesses were removed for the gentlemen who purchased it. I have since done a few things..

1. Converted to 5-speed, removed AT ecm.
2. Swapped in new engine using its own ECM and harness. I was able to wire up some of the needed connections from the F3 connector inside the car. However I am having some issues still.

1. I have no lights, horn, turn etc...Now I know that the lower harness on the S14 connects to the fuse box inside of the engine compartment, however I no longer have the harness. I cant find anywhere on how/pins to find in order to wire this up, and would I wire directly from fuse box to F3 connection?

2. I have read everywhere about the fuel pump relay setup and that its ground triggered, so I have seen people tell me to ground the black/pink wire for fuel pump relay, and I have also read somewhere they recommend grounding pin 1 black/white wire on the fuel pump relay and then my black/yellow should be my hot wire.

Can someone please confirm/assists on my struggles, thanks everyone.

Sorry but you didn't mention if you had used this or not. But have you looked at this page?

This does help, thank you for that. However I am still somewhat lost because I am using a T56 so I didnt plan on neutral safety switch or anything like that. I am able to start the car as I ran my own signal from ignition to the ECM.

Two small connectors with 8 gauge (both white wires with red stripe) connected to power, boom we have power on everything again thanks, hope this helps anyone else.

Gonna bump my own thread again, my car is a 95 with the OBD2 connector under the dash from factory. On my F3 plug I have two wires that say CONSULT, a green/white wire and a green wire. Does anyone know of which is the signal wire in order to read the ecm?
