i installed the kit on my 69. If you know basic wireing you'll be ok. Buy the kit made for your car and it's a direct bolt in minus the grounds....if you have problems painless will help you if you call them
I have a 1990's small block(350) in my car and I plan on some other non-stock items....do you still think that the one made for the Camaro is the way to go and offers enough flexibility in adding my non-stock items?
Is teh Universal kit "that" much more work to use?
I believe that you are right. The universal harnesses will probably need to have an end connection made. Either by splicing or adding a correct connector.
I would stay away from excessive splicing - AT ALL COSTS. Splices are trouble waiting to happen. And especially if you need to do an entire car. Some circuits are more critical than others and any excess resistance will cause trouble. With that many connections you will make a mistake that you will need to track down later. Or one will come loose at the most inconvenient time.
Call painless and ask them if you do need to make the end connections. I have worked with wiring for over 30 years and splices cause many many problems.
