Hi I'm new to Honda Tech . My son and I have a 94 V-TEC Del-Sol with a B16 Head and a B20 bottom. Oct 1st a school bus ran over the front end and totaled it. We now have a 94 SI Sol with a D16Z. When we swap the eng. out do we need to switch the wiring harness also? I would appreciate any help you can offer.

 

No, the same harness should plug right up but you'll have to extend the wiring on the plug for the o2

 

Thanks for the input.
