i bought the truck (93 w250) a week ago. and sinse then the abs light came on with the brake light. as stated in my other post. then i went to wash the mud off the undercarriage had to pull a friend out. and the water in fuel; light came on but is off now, so that must be common? now my turn signals and wipers dont work grrrrrrr. so back to the point. the previos owner has a jacked up wiring situation. looks like every thing dang near is direct wired to the batt. i know this cause all the wires commin of the batt and my a/c blower still works after truck is off. so does anybody know where i can get a complete wiring harness. think i might start from scratch. what do yall think. also does anybody live near pasadena, texas.

 

I think you ought to get a factory service manual to help you straighten out the wiring. Geno's Garage has them. http://www.genosgarage.com/

The insulation on the wires on the WIF sensor is probably cracked. Common. Geno's can also hook you up with a new sensor.

My guess on the wiring is that the truck either has a bad ignition switch or a blown fusible link, and the PO just wired around the problem instead of fixing it.

 

thanks wannadiesel thats a great site cant believe it wasnt brought to my attention earlier.

 

My truck wiring is bucher free,but my water in fuel light will come on after about a 1/2 hour of driving(wif sensor un pluged) can't seam to finned any wires of that loom that are rubbing any ware? O and when i turn of the ign.and back on(Going down the hiway)it will stay off for a will??????????


Eny one no of a common place that thay short at???
Why should it stay off for a will after the ign is sycled???????

 

I'm off work this week , bring your truck up here, witha copy of the service manual , and i will re-wire it for you. I like wiring , and i like a challenge.

 

Try removing the water-in-fuel sensor and with your finger, feel around up in the fuel filter for the spring that holds the filter cartridge in place, make sure it's centered so as not to touch the water sensors probes. Happened to me for the first time in 13 years the other day.

 

thanks for the offer but canada is a lil far sinse i live in texas

 

If short on cash for factory manuel, you might try alldata for $ 25. I have had good results with their drawings. Especially helpful locating wires to make
changes. R C
