Customer Question

Hi, I need the pinout for a 99 tahoe. Its for the connector on the firewall passenger side right below the evaporator canister. I believe its thirteen wires coming out of there.

Hi there.

Rather than the connector location, we need to know what components some of those wires connect to at both ends. Do you have that information?

No sorry, thats why im asking and i guess i also need pinouts for the bulkhead on the drivers side also on the firewall that connects to the fuse box and pcm

I'm sorry, but I'll have to opt out and leave your request open in case another expert has the information you seek. Please do not reply until another expert responds.

I believe that has a VCM and here is it's pinout,

As far as a 13 pin connector goes, I don't see any 13 pin connectors listed. can you tell me the color or the connector also and recount the pins and include any that are blank, too.

Here is the list of connectors, can you tell which one it is?
