Stereo Upgrade Options - Page 2 - ZR-1 Net Registry Forums

Also, make sure that you solder in the 2 required resistors when you install your new head unit, so you're not getting a SYS light in your LCD cluster. Check this link to the TSB, which explains the whole thing.

Would anyone happen to have a copy of this TSB or a working link?

Thanks in advance!

Thanks Jeff!

I'm installing an aftermarket head unit and want to be sure I connect the resistors to the right wires.

Try without any resistor first. I installed Alpine unit in my 91 back in 92 and installed Pioneer Avic Z140BH in 2012. Both time I did not use any resistor and no issue.

Yeah more than likely with auto AC it is not needed.

I'll give it a shot without the resistors. I have a 90' if it matters.

Matter of fact, I installed a Pioneer Avic Z140BH in a 90Z. Had no issue without splicing in any resistor.
