DX harness

i have a 91 civic hatchback DX. when swapping in the b16a1 i will have to modify the wiring harness right? what will i have to do to it? or do u know a place that sells a wiring sub-harness for a DX. Hasport has one for the SI and HF. :confused:

You need to convert to Multi Point Fuel Injection first, then you can use a Si harness and just run the extra wires for vtec and knock.

hasport will make the harness as will place racing, just give em a call and they'll give you the low down.
