SOURCE: Jeep wrangler Fuse box

i had the same problem. i drive a 95 so im not sure if it differs from were the fuse box is. look righ above you pedals to your far left. it should be right there. also if you instruments went out it will be a 15 fuse. its a blue fuse. next my panel went out cuz of the wires on my transmission. if yor looking at your jeep at the front. the wires will be on your left. make sure they are not burned or anything. it will be right on the side of your tranny. mind got burned by the exaust so they were shorting. check that is and see if that is what is it. for a temp fix just put some electrical tap around the wires and you should be set for a wile. good luck

SOURCE: caster adjustment for 1990 jeep yj wrangler

caster is adjusted at the rear of the lower control arms. Camber is fixed and cannot be adjusted by normal means (though special off-set ball joints are available to do that) Toe in is adjusted by turning the sleeves in or out on the tie rod ends. None of this should be done at home though crude adjustments can be made in order to get the front end reasonably straight. Adjustments are made on an alignment machine that allows precise adjustments to all you mentioned as well as front/rear tracking.

So how do you know you need one if you dont know where it is?? Oil pumps rarely go bad unless the engine is sludged from lack of maintenence. After you take the oil pan off, its there hanging down. Make sure you clean or replace the pick up tube. I'm sure you can google up torque specs, for the bolts. Usually there is major engine damage by the time you figure out that there is lack of oil pressure. I would get a professionals opinion before you waste time and money replaicing the oil pump. If the engine has any unusual noise or knocking, its too late.

The wires are a different color on the new speed sensor conector


i guess you dont know that only the main harness colors are standard (jeep) Jeep does no dictate sensor wires.
if the sensor has pig tail wire they are not standard colors. (only pinout matters)
just like the oxygen senors made by all companies.

the sensors are made by many a company and the colors are not standard. only the pin plug are standard.!!! a fact.
see?
why not just plug it in, like it was day one.
my guess, is you dont know the fact above and are worried only?
or is the connector harness all hacked to H3LL. (not stated)

NO ENGINE STATED, so we can really help , see?
