Mild Modifications / wiring dual electric radiator ...
Last post by DocSaunders - June 29, 2026, 07:24:40 AMI need advice on safely wiring dual electric radiator fans on a 1969 Camaro with a ZZ454 and FiTech Go EFI 4.
The radiator failed on June 3. When removing it, I found melted/fused wiring where a 10-gauge fan wire had been connected to what appears to be a 12-gauge wire. The car has dual electric fans. I was told I should use two separate relays, one for each fan, instead of one shared relay setup.
The complication is that the batteries are mounted in the trunk — actually two batteries — and replacing the existing feed wire from the trunk to the front would require tearing up the interior, carpet, and seats. I believe the existing long power feed may only be 12-gauge, but I am not completely sure.
My questions are:
What is the safest way to wire two electric fans using two separate relays?
Can the existing 12-gauge wire be used only as a trigger or low-current wire rather than carrying full fan current?
Where should the relays, fuses, and circuit breakers be located with trunk-mounted batteries?
Since the FiTech fan wire is a ground trigger, what are the correct relay terminal connections?
Is there a safe workaround that avoids replacing the full battery-to-front wire?
I am trying to prevent another overheated or melted connection, not just make the fans run.
One caution: CRG is excellent for first-gen Camaro knowledge, but because your setup includes FiTech, dual aftermarket electric fans, and trunk batteries, also post the same question on Pro-Touring.com if CRG responses are slow or too factory-original focused.

General Discussion / 1968 Camaro Z/28 on eBay
Last post by dannystarr - June 28, 2026, 07:59:16 PMThat's a pretty hefty price for a car with the original engine AND trans missing. Nice complete car already restored and ready to roll. A few other issues include WP bypass MIA, '69 style front spoiler, underside cross plate where everyone jacks it up is SMASHED in quite a bit. They say 25 to 35% for NOM. Lets go on the low end and say 25%. And another 10 to 15% for the trans. We'll put it at 10%. Puts it at about $84,175. That seems about right.

Restoration / Re: 69 4 blade fan orientation...
Last post by KevinW - June 28, 2026, 04:14:57 PMTime to revisit my post. Turns out the Crane adjustable vac can has been going bad for a while (totally dead now), causing me to advance the dist and increase the idle speed to compensate. Also found a cracked vac hose. So replaced the can with a B1 and fixed the hose. Set timing to 4BTC, and running much better. Just had some ping when it shifted to 4th and locked up (200r4) under hard acceleration. Replaced the stock mech advance springs with a stiffer set and all good now. Temp at thermo is 205, rad tank is 185. I am happy with the performance now.
I had a little side task when my anti-dieseling solenoid shorted and fried the fusible link. Got that replaced and ordered NOS solenoid. Still need to put that on and adjust the accel pump rod (QJet).

1968 - Orphans / LONG SHOT - 18N399408
Last post by wcgould - June 28, 2026, 01:20:38 PMWe have owned a 1968 z28 badged camaro for a number of years with a 454. It has a 3.73 rear end a Muncie M21. A Clock tack 6000 rpm redline. Looking to see if it was real and there is a 302 out there that needs its original home 18N399408.
