Stupid head unit question

Hi all,

I bought my YJ without a head unit, and finally got around to getting on the other day. I've never installed one before, but everything I've read said it was supposed to be pretty easy.

I ordered the unit from Crutchfield along with the wiring harness below:


I understand that I'm supposed to wire this up to the wiring harness that came with the head unit, but I think I'm missing the piece that the plastic portion is supposed to plug into..

Looking into my dash area where the unit goes, there's just wire:


Am I missing something here?? Thanks!

Looks like the previous owner was a hack and just chopped the factory harness off.

unfortunately, yes. I would use solder and heat shrink tube for the install. However, twisting the wires together and electrical tape will do the job.

Here is the wiring diagram http://www.modifiedlife.com/1989-jee...iring-diagram/

Well I guess it's not too much more work than splicing it with the other harness, thanks for your help!

You could also use crimp on butt-connectors to make the connections. Wrapped wire with tape over it is prone to vibrate loose.

Those should work too. I'm just not a fan of holding an electrical connection together with tape which degrades over time. Something resilient to vibration or motion holds up better.

This. Solder and heat shrink is the way to go.

You also have the option to go to a jy and get that harness plug out of another Jeep (same yr/model). And color match the wires to the wires in your dash, plug it in right this helps for when you may want to change the deck again.

you can buy reverse wiring harnesses to replace the missing factory plug.

Throw a pair of wire cutters in your pocket and find a jy that let's you go get your own parts. Tell 'em you're looking for certain bucket seats and find that harness instead.

FML, the master cylinder on my clutch went bad before getting to this. Now I have the jeep back and just realized I need one of these as well, unless someone has a good alternative?

Unless the deck you're using is ancient, it should have a sleeve with tabs. Put the sleeve in the the dash and use the tabs to secure it. Then attach the wiring through the sleeve and plug the stereo in till it locks.
