Yup, My Flexalite Variable speed controller Is Chit. Left my truck Idleing for 7-10 minutes while my wife was doing some real estate stuff. got in to go and the temp was 250*+, fans wouldnt come on at all. had some hiway driving to do anyway so alls cool (some pun) but now have no way to controll them. I can jump them togther and make them run. whats the best way, relay harness? (don't know if my pcm is programmed for it) or can I just get a probe that turns on a relay ( I would do two at two different temps)
who's had luck with what, Thanks

Nelson who is a sponsor ----> makes a nice fan harness. You just need a tune in order to activate them in the PCM. Maybe you could kill two birds with one stone, get the harness and a tune all at the same time.

Also check out PCMFORLESS, they do they same. That is who I had my mailorder from a while back.

Good point, we have several sponsors who can take care of you.

Same thing happened to my Flexalite controller. I wired it to a switch - works great, especially in the staging lanes at the strip. Just don't forget to flip it on when you need it lol.

The Dakota Digital and DCC unit are the only ones that are worth a ****. Or just get the harness from Allen.

we should make it a sticky for people to throw away their flex-a-lite vsc's. i have a nelson harness with a wheatley toon and its 10 gagillion times better than my vsc that crapped out in 3 weeks.

I made my own. Both fans run on low all the time, until I kill them with a switch. Then both fans on high when the A/C comes on.

I made this for under $60 bucks, with extras left over. I went by this diagram, but reversed the grounds for "positives."

Works great no problems. PM me if you'd like some help.

I can tell you exactly what causes them to fail, and how to prevent it, but I don't think anyone here is in the listening mood for that
