Do non-Monsoon H3's have wiring and connectors for the amp/sub?

[Jeepwalker]

I was wondering if they are all wired for the amp/sub assembly even if it's not present? Mine has Monsoon, but just curious in case I were to buy another that didn't have it. I know I would need to change/modify the rear plastic panel.

Thanks

One would like to think they use the same wiring harness regardless of options, but really the answer to that is a hard no. Even more so with the Monsoon vs standard stereo, the wiring for the speakers is totally different between the two. You will have to find another H3 with the Monsoon system to get a replacement wiring harness.

Generally speaking, anything that is a factory option vs dealer installable will use a specific wiring harness for those options. It is pretty rare to get unused wires in a harness, regardless of the brand.

Thanks. You're saying a hard 'No' because you've looked, right? (just checking). I pretty much figured this would be the case, but want to double-check with someone who's put their eyes on the situation.

Thanks!

GM is not known for universal wiring harnesses to fit all optional buildouts. I had an Audi for a short while and that wiring harness did come with terminations for optional equipment. I had not seen that in other vehicles.

Yes, I have gone over the wiring schematics in detail on the H3's and there are some big differences between the options. I've looked at several options on my base H3 I used to have and found no wiring for them. Even my Alpha that is mostly loaded out still doesn't have wiring for the few options it doesn't have. The Monsoon system is wired completely differently from the standard stereo, there is no way they'd have the harness be able to support both setups. On the standard setup the wires for the speakers go straight to the stereo. On the Monsoon they go from the speakers to the amp above the rear wheelwell, and then the amp is wired to the stereo. Lots of extra wiring compared to the standard setup.

They stopped using universal harness style wiring in the 90's, as tech increased and also to push buyer's into a higher optioned vehicle.

I’ve ripped apart monsoon and non-monsoon H3’s. Different harness. Verified with my own 2 eyes. Same with the power seat harness and other options.

Thanks a bunch guys. I appreciate the info. That'll help me while looking or the next one.

Cheers!
