Hello, I'm new here I just got ahold of this 89 iroc-z. It has an issue where when you hook the battery up the parking lights stay on? Even when the key is out. I read where the radio could be the cause but I took the aftermarket radio out completely and it stays on? I'm not sure if this is the right forum for this but figured it had something to do with electronics. You guys got any ideas?

 

The park lights and even the headlights and brake lights will operate with the key in the off position. This is a safety feature.

If the light switch is in the fully off position, either the switch is bad, or someone hacked up the wiring.

Pull one fuse at a time until they go off, then you've isolated the problem to something in that circuit.

 

I had another question not related to this but it has a 110 mph speedometer?? Does than mean it could be a fake iroc..?

 

There still seems to be a Debate over this.
There are good arguments for both sides on this Forum.

I went searching for Original-Documents at the closest GM Corporate-Office, to where I live.
This was in 2011, in NY.

On many occasions... I have found that many GM Documents, that contain any information concerning sensitive topics...
to be intentionally unclear in vernacular, structure and any definitive terminology...
appearing to be written/ typed by Lawyers/ Legal-Professionals.

My best guess, from reading GM Documents from 1986/ 1987... regarding the Camaro.
It would appear that certain States and Automotive-Insurance Legal professionals were pushing GM/ the Chevrolet Division (and even the Corvette Sub-Division)...
towards the use of the 115/ 110 Mph Speedometers over the 145/ 140 Mph Speedometers, for the majority of Camaro Sub-Models.
There was no specific mention of which Sub-Models (Sport-Coupe, Berlinetta, LT, RS, Z28, IROC-Z28) were of more concern.
However, there seemed to be less fuss, in regard to "more expensively built" Camaros...
Maybe the Government was content, when receiving more Tax-Dollars from Higher-Priced Camaros.

I do not believe there will ever be a clean-cut answer...
Everything written on this matter is as un-clear and vague as can be!

 

Yeah mine has a 305 TBI and a 110 speedo but I know the original owner who bought it for his wife and the other two owners just really let it sit and didn't do much but drive it a small bit and out a fuel pump..it has has rear drums.
