Can I use the 94 integra under dash harness to control the gauge cluster so I wont have to cut anything? Just plug it the plug by the ecu where the stock unit plugs in? I am getting rid of the heater core so i dont need to worry about that.

ive hear it is, but when i did an integra dash swap years ago, i remember have to cut off the teg ends, and splice them into the civic harness.
still got the harness in fact if you just want to buy it.
never could figure out how to wire up the dimmer and rear defroster though

 

Well, this is partially correct. You don't actually have to cut any of the wires, just push the connectors out of the plug itself, then push them into the civic plug and voila.

There is only one plug that you have to do that to. The other two plugs are the same as the civic ones and will plug directly into the fuse box. You do need to change one other wire around on the blue plug.

I would say, as long as you have a complete civic harness to look at, then you can compare the two and match up the wire positions very easily, as most of the wires are the same color for the integra as for the civic.

It is really pretty easy, and I think that using the complete teg harness is the easiest way to get everything on the dash to work like it is supposed to.
