Hello,

I am going to do a 3800SC engine swap, but the part which scares me is the wiring. I am going to buy a pre made wiring harness, but I honestly know very little of wiring in cars. It's just a big mess of wires to me. I have been doing research in how to do wiring stuff but it still looks really hard.
Any tips or someone with the same problem who found out it isn't as hard as they thought it was?

Thanks!

A pre-made harness takes 5 minutes to plug in. You'll be fine

As slammed has replied, there is no wiring with a pre-built swap harness. Plug the connectors in, reprogram the PCM and you are good to go. Now if the question is how is the harness made; it is a combination of the Fiero harness and the 3800SC harness. You would need to know how to run wires and work with pins, connectors and the crimping process that puts the wires on the connector pins. There are a few guys on this forum that make harnesses and they can also be found elsewhere.

I know there has been some unfavorable talk about him but I have to say he has been very helpful and attentive to me and I personally have zero complaints about him.
