Decided to upgrade the WJ's clunky old headunit with something more modern. Used a Connects2 harness adaptor so no wire cutting.

Problem is the Jeep's aerial plug bears no resemblance to the adaptor I got with the wiring kit.

I read somewhere Jeep changed the aerial fittings on post 2002 or 03 WJ's but I can't find that info anymore. Everywhere I look I find the same adaptor that I have.

This is the factory plug:



Jeeps are fairly exotic fish in the UK so there isn't much knowledge on them.

IIRC this adapter is the one you need. It's been a while since I swapped mine out, but I think that was the one I got.

Thanks. That one is to use an aftermarket arial with the oem headunit. I need it the other way around, i.e. oem aerial to aftermarket headunit.

However, your link lead me to the Metra 40-CR10 Antenna Adapter which I think is what I need.

I used a Metra 70-6502 harness kit and the 40-CR10 antenna adapter in mine. I cannot recall any issues. Metra has become my standard in the last 10 years. They are quick and easy if you know what you are doing, but are short on instruction if you don't...

Yes, the Metra 40-CR10 antenna adapter or the Connects2 CT27AA24 Aerial/Antenna Chrysler Connection Adaptor are the ones to go for.
Here in the UK Jeeps are quite scarce (like Land Rovers in the US I guess) so getting even simple parts can be an uphill struggle

Now, does anybody know if the late WJ's have an aerial amplifier ? Since the aerial is in the RH rear side window rather than an aerial post I'm guessing they must have.

Reason I want to know is, FM/DAB splitters don't work if there's an amp in the circuit.
