Just in the process of changing my switch - any tips on threading the wires up and down inside the column Steve?
This parts breakdown might help you with the bearing
Hi Bill, yes, threading the wires, it's the toughest bit, ! However this is what I did.
The wires at the block connector can be carefully unclipped. Use a very small screw driver to carefully push the clip to release it from the block connector, leaving the wires together with the clips. BUT
1.Take a photo before starting ensuring you can tell which way around the block is.
2. As insurance I put a piece of white tape across the connector and wrote the colour of the wire above each port. EG W= White etc ( think there was LG light green, and DK dark green)
3. Unclip
4. Cut the OLD switch wires at the top as long as possible.
5. Tape the new to the old at the top (steering wheel)
6. Pull through from the bottom.
7. Push new wires back into the connector ensuring correct order & right way up.
Now I can tell you that mine was very tight & jamming, so much so, it parted company! Mine is T&T & I imagined keeping the column straight would be best
However if you tilt down a little & use a torch from the bottom up, you can make a clear passage. I use a thin flexible steel rod to restart the process.
I should say that this info came from Wilcox Corvette Technical, with the exception of my bodge!! LOL

I'll post it if I can find it. Steve
