ok i need to have vtec wired into my 94 ls, to do this i was just going to buy a 94-95 gsr wiring harness. well i found a 92-95 dseries vtec harness (engine hanress only) the guy says it will work for the b series also, and all he has is the engine bay harness. i guess my question is. will this work on a bseries and do i need the cab harness, he says its already wired for vtec. let me know guys

 

uhhh, why dont you just get a couple wires and pins and pin the ecu and run it to the solenoid and pressure switch and run another ground wire and save your self some time and money of swapping harnesses.......it takes 10 minutes to run the wires from the ecu to the plugs, you can get the plugs and wire them in, so it looks clean, but i guess your gonna do what you want........thats what i did on mine and you cant even tell its not stock unless you really look.........

 

Just add the wires you need, it's much simpler, cheaper, quicker, and easier than swapping out an entire harness.. The D-series harness may or may not be missing the knock sensor wire which you may want if you're using a GSR/ITR/B16..
