get an obd-1 distributor and obd-1 wiring you'll be all set.

You could use the cx wiring, and add the vtec wires. Check out hybrid.honda-perf.org for the wiring diagrams if you think you can do it, it'd save some cash.

What kind of obd1 wring will i need n will the car start up with or with out check engine light

Any dohc vtec wiring, b16a, gsr will work.

If i splice the cx wiring will the check engine light come on because of the knock sensor or do obd1 engines have knock sensors i dont want check engine light because i heard the engine runs in safe mode because the ecu thinks something is wrong with the engine, safe mode wont let the engine wont run 100%

As long as you have an ecu that is wired for a knock sensor, and you do with the gsr ecu, u will need knock sensor to avoid CEL...however, the code 23 knock sensor CEL will not put the car into limp mode, but still should have regardless.

The LS block does not have a knock sensor, so it would be a good idea to either get a hole drilled to mount the knock sensor (do a search), or get it chipped to run without it.

But with the code 23, vtec will still engage, the timing may be retarded a degree or 2 though....it will run though.

Best bet, get it chipped.

Where can i send it and how much$$$ will it get cost to get it chipped thanx
