i own a 89 hb and i purchased a dohc zc motor my only worry is i dont noe what engine wire harness to use to get this kid running

thanks to all the help

 

use the engine harness from the engine that came in your car and modify it as needed - if you have Si model, it will only require a minor change at the distributor - if you have DX or STD model, you will need to do the DPFI to MPFI wiring changes
