(1) There is a snap connector with a worn red wire that I want to replace and was wondering if there was a way to remove the red wire from the male connector that is in the rubber connection block without destroying the block ... or do I need to replace the entire connection assembly? Also, does anyone know the function of this assembly?

(2) There is a little round disk attached to the side of the tranny with a rubber tube coming from it. This tube has been rubbing on the frame and a hole has nearly worn through. Does anyone know what this tube does and how to replace it or whether it would be better to just wrap it with rescue tape and leave it place?

Thank you.

Memory is the second thing to go, but if it still serve me, I believe the round thingy is the throttle position indicater. Determines how far you have pushed the throttle down to change the shift points.

With a needle or jewelers screw driver you can remove the wires from the connectors.

Thanks for the feedback, Gary. Sooo ... is it a vacuum tube? Any idea if the tube that comes from it is easily replaced? I hate to pull on it and destroy it in the process.

How do I use the needle or jewelers screwdriver to remove the pin from the connector block?

Vacuum tubes are those funny old things that glow inside a good amp...

There is a small tube tool that is used to free the pin in the connector. It is inserted in the male end and it compresses a small spring finger so the wire and pin can be pushed out the end where the wire is. This tool is available at electronics supply houses. I would but the tool and a new pin for the connector and then replace both at the same time. Do not use anything other than the insertion tool or you will destroy the connector and the new pin will not seat properly.

Old fingers hit something - The proper sentence is "I would remove the old pin and wire and replace them both at the same time"

Agree with Tom K, use the tool, You can get it at any auto supply house that sells replacement connectors similar to the one you have.

Not vacuum. I think there is a cable inside that goes to the throttle somewhere.

The function of the snap connector is to allow easy assembly and testing of a wiring harness. I would just use the remaining three wires in the snap connector and section out the one bad wire with a butt connector with heat shrink. If a mechanic needs to get in there, he will.

Wire Range - Color
22-18 gauge - Red
16-14 gauge - Blue
12-10 gauge - Yellow

You'll need to heat up the plastic coating to wrap & seal it around the wire. This will keep the moisture out. Too many times people use this type of wire connector and never melt the wrap. A simple lighter will do the trick... only melt enough to wrap it or it will split.

As far as the tube goes... I'm on vacation right now and would have to get back home to look it up, but I believe it to be the TPS cable. If it is only worn through the thin plastic coating I would just wrap it up with good quality tape and leave it be... If it's worn through to the cable, change it out.

Do you see something that looks like a metal spiral wrap underneath where it's worn? Can you post a better image of the worn out section?

I never knew that the extra tubing on butt connectors was supposed to be for heat shrinking to seal the connection but it certainly makes sense. Thanks, Bill. The problem is that there are 2 butt connectors on the wire and they are causing the problem (sloppy installation). My intention is to replace the damaged length of wire and sloppy butt connectors with a new piece of wire that connects directly to the pin in the connection block and a SINGLE heat shrink butt connector correctly installed.

The location of the hole in the tube is nearly impossible to see as I only found it by feel as I was securing some loose wires, with wire ties, however, your explanation of there being a spiral wrapped wire inside the plastic tube makes sense as the tube is fairly stiff. I am going to wrap it with silicone "rescue tape" and put a lenght of "smurf" wrap over that.

I appreciate EVERYONE'S help with this. ... off to the store for the connector tool! Carl

Just so we are perfectly clear - This style is NOT heat shrinkable.

This style IS heat shrinkable.

Thanks for the follow-up re the difference in connector types. I have the non heat-shrink type.

Ideally, you would use the "Non Heat Shrink" INSIDE your coach on any INTERIOR wiring connectors as these are not subjected to water road spray.

You would use the "Heat Shrink" connectors on any wiring that would be subjected to moisture.



Here's a piece I did several years ago on this same subject.

Failed wiring and how to protect against it. FYI...

The heat shrinkable connectors are available at Fastenal for about $10.00 for a package of 25 for us that don't want to order $300.00 worth.
