I have a 85 Iroc with 5.0 (LB9) Tuned Port Injection and I have a Summit Racing cooling fan switch im looking to install. I am just wondering where it's located on this vehicle? Instructions say most likely on pass side head between 2 spark plugs but i dont see anything? Any ideas???:o

I think on the tuned port it's on the intake manifold by the thermostat. on the TBI's it's on the passenger head between the two rear cylinders. I hope this helps.

I have an 87 Iroc 5.0 (LB9) and it is on the pass head between cyl 6 & 8. You need to get to it from the bottom if you still have your exhaust and all the other crap still on the engine but you can get to it.

thanks for all your help
