Hey was hoping someone could ID these plugs for my sons RB to S13 swap. We bought this motor with the description "uncut harness" but found multiple loose wires, plugs and a smashed ECU plug. Repinned the ECU plug and think I have the inside wiring figured out but some of these under hood connections I have'nt been able to find yet. Where we bought the engine gives a 30 day start up warranty which at the time you figure should be plenty till you start really checking out the harness with the other mechanical fab work. First pic is 5 wire 6hole plug about 8 inches from where main harness enters engine bay.



Next two are in group of wires heading to mass air .Also anyone know where I might get the correct end for RB mass air wires? (ours were cut off)





Also hoping someone could Id this

Thought I would show my engine mounts, might help someone.(sorry McKinney' I could'nt afford yours) also I think solid would be better with how close oil pan to rack and dump pipe to steering worked out on mine.





Thanks in advance to anyone who can help me out. I just want to get this to the point I can fire it up before the warranty runs out. I've done a compression check and looked at the plugs but would like to here it run then go back and really fine tune everything with a litle more peace of mind.

^^^ Correct =]

Just in case anyone needs the info, when connecting the wipers in an S14 swap, you need to repin 2 connectors on the wiper amp plug. Switch the large brown with the small brown/white and vice versa. On the plug going to the wiper motor, cut the plug off your KA harness... Connect wires as follows:

LG -> L/RO -> OB -> BLG/R -> LG/RLG/B -> LG/B

Hope this helps someone =]

Hey thanks just one question, "EFI plug for wiring" as you stated, does this plug into something I dont have or am I wiring this into something?
