Will an obd1 complete harness from the engine harness to the harness that runs to the ECU fit all the connections inside the EK chassis? Basically i bought a complete obd1 harness and swap and i need to know if it will connect to any plugs that are in the cabin of my EK if there even are any.

 

i dont think it will...if u have a stock engine harness use that to do the swap instead it will save u time and money and its easier

 

Are the non vtec ek harnesses prewired for vtec like some of the EGs are?
Mine is a dx hatch

 

i think only the EX and SI came wired with vtec..cx,dx, and hx didnt have prewired vtec...when doing a swap from non vtec to vtec, all u have to do is find some extra plugs that fits the sensors u need to hook up like vtec, ks, etc and wire it straight to the ecu simple as that

 

no there not but they can be modded to do so if you use a obd1 harness you might kill yourself trying to find out where the wires go

 

the HX is VTEC, you only have to rewire the O2 to work with the 4-wire instead of the stock 5-wire O2.

OP: anything can be made to fit and work. Personally I'd start with your stock harness and make it fit on the engine and run the wires that would be needed to make things work.
If you need OBD1 plugs to plug into the engine, then convert your harness using your OBD1 harness.

 

Oh i know all about the splicing game, swapped many of motors and obd's to work with different chassis. just wasnt sure about the incar side of the harness. Guess i be wiring some vtec up on my obd2 harness. Thanks

 

my brother has a EX harness for his swapped B16 EK, vtec works, but check engine light is on... can someone tell me how to fix the problem...
