98 Cherokee wont shift into overdrive

you will need to interpret the diagrams.
getting a color picture of this is unlikely BUT I will try.

attached is diagram of switch - terminal 4 will have 2 wires tan and black stripe (TN/BK) and they should have 12v on both. SHOULD is key as we ASSUME wire from fuse to switch is good.

the idea is to get 12v to the DLC cavity 16, either repairing the circuit to switch or jump voltage with the clip on wire lead.

 

terminal 4 the 2 wires 1 to DLC other to fuse

 

Are you around.? Im finally going to work on this...plz tell me where im jumping voltage to terminal 16? Am i taking the headlight switch out again and jumping power from that to the DLC. DLC is the port to connect a code reader? We are tryinb to get voltage from headlight switch to the DLC. DcL = code reader port? I see picture, that picture is the headlight switch?

 

There is absolutely no voltage to connector anywhere

 

Rdd 4uy

I was wrong seems like this one had.most power

 

Ok tan black wire has power, but not all slots here gave power

 

Ok i get it now..so how an i jumping from tan/black wire in headlight switch whicb one goes to fuse other to dlc 16

 

I understand now...im goinb to peierc tan/black wire and clip the one not going to fuse then pierce tan/black on dlc #16 connect other end if clip..? Confused about fuse..i have a jumper fuse

 

I GOT IT!!? # 16 on DLC has power i go to autozone to see if pc codes work

 

Ok got power..but now another problem..my gages dont work when i have power to dcl..but if i disconnect it, my gages come back..what the hell..i got my entire dash apart

 

Omg now it shifts into drive as long as my gages dont work right and engine light out. if i disconnect my wire go dlc, gages work but jeep dont stay in drive no more then 10bsecs like b4. Lol

 

Ok. I checked that i got voltage to DLC from light swith...but im at advanced auto and STILL cant communicate.
Now Im totally clueless..ill post to see if others can help in meantime till o here from u

 

post an update -

Did you get 12v to DLC?
Is the 12v present when probing cavity?
Is the 12v there with key off and engine off?
Does it (12v) show up only with key on or engine on?

 

Ok , this is what i did..spliced tan/black wire from light switch,
Then spliced tan/black on DLc...
Then there was voltage..BUT, MY dash won't work when its connected..
While I have it connected...my jeep did shift into over drive ( still no reverse lights) so when my dash goes out, the engine light is gone...
So
.went to autozone, while my jumper connected and DLC has power..
Still can't communicate
I followed your directions on my other thread. Did i do this completely wrong?
