I bought a d15b from a guy locally. he had it in a crx dx, but had to part the car out due to body damage. it came with a chipped ecu, but he ran vtec to a switch.I want to wire it to the ecu. My si is already mpfi so what i need to know is how to wire the vtec and if i will run into any other wiring snags. Also have a MSD 6al ignition setup that i will need to figure out. any help will be great.
