2 issues - timing and pcv
I need to set base timing on 1990 Suburban 4X4 1/2 ton. What color wires do you need to disconnect the computer and where are they located?
I also removed the emmission pump but now I have a open hole on each valve cover. I have been told I still need to install a PCV. Do I need one for each side? How does the tubing to and from the PCV route? Thank you in advance.

You should be able to put a universal crankcase breather in each valve cover. They are available at most auto parts stores.

To set the base timing you miust disconnect the tan w/ black stripe located underneath the plastic cover on the firewall.The fuel pump relay is also located there.
The wire has a single contact weatherpack connector.Once disconnected you can then set the base timing. chuck's

Re: Re: 2 issues - timing and pcv
Hey, I know this is an Older thread, BUT, in my own quest to find this single wire connector to disconnect for setting the Base Timing, I have been led astray by about 2.5 feet.... My connector was on the DRIVERS side engine compartment firewall near the windsheild wiper motor. Took me FOREVER to find it!!!

Sometimes it's behind the glovebox too.
