more info!
are you using the s14 wiring, engine, and manifolds, or the s14 engine with 91 wiring , 91 intake and exhaust manifold, and 91 distributor? hopefully you made it easy by using the 91's wiring. because if your using the s14 engine harnesses i belive that the mystery transmission harness is for a crank sensor on the s14 transmission but IDK.

i bought da engine from sum kid he said that the wiring was made to work with an s13 so im preety sure its s14 wiring(plus the connector under da dash that runs off the ecu wouldnt fit so i wired it off ma s13 harness to fit) but ma lower harness is from the 91

this is sum random wire dont know where it goes or if it is even important but it is part of the 91 lower harness nd is right next to the fuse box nd tb and yes my alternator is hooked up

Image

this behind the intake inside near the brake booster this is part of the harness attached to the motor wen i bought it dis was like this ne thoughts on this??(yes is s14 harness)

Image
now this is the plug for the transmission that jus sits there that is a s14 transmission nd a 91 lower harness
Image

this is wat i rewired that was in the dash preety sure its for accesories this plug(white) wuld not fit so i wired them my self now the wires cut off to the side was like this already dont know y but guessin it was s14 s%*# so i only rewired wat they originaly had wired so do i need these or not?? this is the reason y i assume it is an s14 top wiring harness plus its wat the original owner stated but pls correct me if i am wrong(wires that are connected blk,orange,yellow and red, and yellow and green, and blue)Image
