Re: swap q's
I am not the most experienced guy on this board but I just got done taking this all apart. If it was me I would go get the double fan from a junk yard that connects to the tpi system. TPI cycles it on and off and the relay from what I can tell would not just plug in to a TBI single fan. I am having to do the reverse and have to get my tpi fans to work with a holley stealth ram wiring harness so thats what research I have put into it.
