No I'd leave those empty. Must be the fuse box in the engine bay they are talking about

All the gauges were acting goofy,Shorted out (bcm)
I think that FSM also had a 96 or at least seemed start to cover the newer 96 up. I thought the PCM was on the fender behind the air box until at least 95. Maybe the 97 up changed location. I pretty sure the Grand Cherokees did but that was also a new body style.
So the new clock spring shorted out during testing? What the hell?!
Not sure about the PCM connector testing on the XJ, did limited testing on a old Toyota which was straight forward.
Edit: if the new clock spring was bad it might explain everything including the cruise control.
I did a bunch of continuity and voltage checking today. I have a questions:
- Is the PCM right next to the air box. It sure looked like the right thing to me, but the service manual said it should have been by the firewall... Anyways, I used that connector to do most testing and it seemed to be doing what it should.
Anyways, I tested the brake switch, the cruise control servo, vacuum, cruise control switch, and they were all good. Then I switched to the pins at the PCM connector and started getting some goofy things. I would definitely get voltage fluctuation where I should have it, but everything should be reading either 12V or 0V depending on what I was doing. Instead I was getting some 12V and 0V, but I was also getting some at like 5-6V and then when I'd hit buttons that should have brought it down to 0V, it would only drop like .3V's lower (so nowhere near 0V). Then the clock spring started smoking...
I cannot imagine a reason for it to short out unless it was sold to me defective in the first place. Any thoughts? I'm reaching out to 4WheelParts right now to try and get it warrantied out, but they specifically say they don't warranty electrical parts... Which sounds like BS.
I hooked up my old clock spring and it didn't smoke, but it is definitely warped. I decided to take it apart to see the insides anyways. It definitely got fried! All the wires are melted together.
It's too bad that they go straight to the PCM without a fuse I can find.
