I have an 86 Iroc 305. It was wrecked, and the fan was taken out of it.. i noticed that the wires were hacked up in it as well. I have an 87 Iroc with a 305 as well.. it has the dual electric fans..
Everything is there. I wanted to know what all i needed to take out in order to install it in the 86..
Thanks

 

Easy swap....but what do you mean by hacked on ur 86's wiring?

On the 87 there should be plugs for each fan, they should run to a relay on the firewall.

Trace the wiring where plugs into the harness and unplug it.


I always then wire a switch that acts as a ground on the fan relay so it turns on both fans via the switch if needed.

 

okay.. doesn't sound bad.. here's what i mean by the wires were hacked...
See the brown wire hacked into the large orange one? it runs all the way around the back of the motor right next to the battery.. Tell me if i'm right but is that the constant power to the fans even when the car is off?
and this green wire is hacked off as well.. if you could identify these for me I would greatly appreciate it..
I have the car in primer and I want to get it running so i can drive it into the paint booth
