B16a2

i have a honda del sol with a d15b7 in it right now if i swap to a b16a2 will i have to change the wiring harness or will the harness come with the motor and tranny?

most times it won't come with a harness, depends who you order from. If anything you just have to add a few wires and the ecu.

Check Hmotorsonline.com. They all come with harnesses. For a swap into your car as long as you use the B16 harness you'll need run 2 wires for VTEC into your car to the ECU.
