installing ecu

[crx hf]

I wanna know how to install an si ecu in my HF before i buy it from mellowboy.

Why would you put an SI ECU in your HF - do you have an SI motor?

EDIT: Just read you haev an SI motor. To uninstall your old ECU you just unbolt it, and pull the clips out. Plug the new one in and bolt it back up.

I dont think its as simple as that, I think you have to run a couple more wires.

Uhhhhh hey has a swap, shouldnt he have already taken care of running the wires?
