Centech / Taurus 3G / Mustang EFI Harness / Taurus Fan

I have these 4 elements in play and will be hitting this wall pretty soon on the build (soon being relative I guess).

Anyway, I figured someone had 3 of the 4 or 4 of the 4 in their build that I might bug about tying it all together.

Brian cleaned up my EFI harness already but none of this was in the discussion yet.

Thanks!

Are you controlling your fans with a thermostat?

1. Centech-to-3G = Just one wire from the harness. All the others are up to you. The Green w/red wire from the 3G's plug will need 12v with the key in RUN. The Green wire from the harness that was meant for the original body mounted voltage regulator is the perfect candidate.
You'll have to make your own charge wire, or purchase a pre-made one like this: http://www.wildhorses4x4.com/product/Battery_Charge_Cable_AMG_fused that we sell for high output alternators.
The original Yellow charge wire can be re-purposed.

2. Centech-to-EFI = Just three connections. Any full-time 12v source, any switched 12v source, and any 12v in START only source.
Is this a factory Mustang harness that is re-worked, or one of the aftermarket setups?
Will you be running an automatic trans, or a manual?
Those two aspects can make a difference in the most convenient connection points.

Waiting to hear what you intend with the fan, but the Yellow 10ga charge wire you're not using for the alternator any longer could be used easily to power up a relay setup or whatever you end up doing for the fan.

Thanks guys.

Planning on running thermostats Been looking a a couple of harnesses for that fan that have the two relays and I think a switch to shut it off completely for water crossings.


Here's an aftermarket

Also looked at the Volvo relays on ebay.

Harness is from a 93 mustang.

Thanks!

Here's another one. Customer service has mixed reviews but performance history seems to be good. I have emailed asking if the relays are replaceable and how easy they are to find.

Fee wire nuts and some black tape and it should be fine. LOL
