It's a Cherokee Laredo 2.5L. I am working a lot on this vehicle I've
been using now for a couple of months. I love this vehicle.

Thanks for the link. I believe the switch is okay as I've already done
the continuity test the article mentions . I've checked the "reverse"
pins (A-E) on the switch and I have no resistance when reverse is
engaged (circuit is closed) and no continuity when reverse is not
engaged (circuit is open) so I assume the switch is doing its job. The
Haynes manual mentions the wire before the switch is hot at all time.
By "hot", my initial question was to know if I can connect it directly
to the battery. So far I haven't found 12V on this wire so I am
tempted to bypass this wire but I prefer to be sure before doing that,
I won't kill the safety switch. As pin "A" is also responsible for
1-2nd speed and 3rd, is there a way to test those modes are engaged ?
The differences between D, 1-2 and 3 are not striking a lot to me so
far. I guess I should be feel a difference and so far I am not.

Re: Backups lights not working on Laredo'91
 

Does your rear window defroster work? I 'think' it is on the same fuse
as the back up lights.

The rear defroster light turns on when I press defroster therefore I
assume defroster is okay. I checked the fuse box under the hood and
the one on the driver side. All fuses are okay so maybe the wiring
harness is cut at some point. I have 0.4 ohm of resistance (could
probably have more with cleaner conductive parts) between pins A-E on
the neutral safety switch plug when reverse is engaged and no
continuity in all other modes.

With engine on and off, I never read any volts where I guess I should
read 12V (before the switch to pin A) so I am thinking of bypassing
this apparently cut wire by adding one with a 15A fuse hooked directly
to the + of the battery. I based my plan from the wiring diagrams in
the Chilton (it even has a correct color code for my jeep the Haynes
does not have). Applying directly 12V on pin E turns on my backup
light so the after-switch part of the circuit is good. Any comments/
tips on my plan ?

I'll post some follow-ups on that.

Another question: my parking brakes are fine but the button to release
the lever has a very small course, maybe 4mm. I don't think this is
normal. Is there any way I can unstuck this button assuming this its
course is not the regular one ?

Thanks
