Default Racetronix Kit

Hello,

I'm installing a 2003 5.3/4l60e into a 1978 Caprice Aerocoupe. It's going to be a simple swap over with no engine mods. I'm installing a gas tank from a 1995 Caprice that's setup for EFI. I'm considering this kit from Racetronix:
Racetronix Kit

Is the kit in the link above (RXP255) what I would need to power a 5.3? It seems the harness in this kit is designed to plug into the factory 94-96 b body bulkhead. What would I need to do to integrate this kit into the 2003 harness that I will be installing? Would I be better not to use this kit since it's not actually going in a 94-96 b body?

thanks
Brandon

Why not just use a regular relay setup that just needs the one power wire to turn on the fuel pump from the ecu.

$265 seems crazy when what looks to be basically the same thing is $65 https://www.racetronix.biz/product.asp?ic=fpwh-026
I have one of these Racetronix kits and it's fine, though these guys are far and away the worst people I've ever dealt with in terms of customer service should you have even a simple question. It's like dealing with 12 year olds and a complete waste of time. Would never again use them for anything, especially since this kit could be made at home in 20 minutes for $20.

Thanks for the responses. My attempts to deal with them were very similar. After seeing their lack of concern about questions and custom support I decided not to use their company, as opposed to Griffin Radiator. When I called Griffin I spoke to a person who was very knowledgeable about the product and seemed happy to answer my questions.
