need help with d15 v-tec swap

Whats up guyz.I purchased a 97 d15 v-tec an wanna put it in my 91 dx hatch.Now i was told i could keep my stock ecu an wire hanress an conect v-tec to a tockle switch.what do you think about that or how can i keep my stock wire hanress an swap a new ecu into play by keepin the stock dx wire hanress?email me throw my email not here [email protected]

you can also wire your vtec to a stand alone shift light. keep your ecu.

if you wnat to keep your stock ecu then you gotta switcht he dist and intake mani over to your new motor. if you want to put a obd0 mpfi ecu, then you gotta get a obd0 mpfi dist and complete intake mani. if you want to run the obd2 intake mani, you gotta do obd0 to obd1 swap, you can use the dist and injectors for obd1 but i would recommend a obd2 hanress to steal plugs off.

always modify the stock harness
