idiot light -> gauges dash swap ?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

shifty · 06-29-2005, 11:22 PM

Note: I already read the FAQ post about how to do this conversion. I read the page it was linked to and got the idea: I need to swap some wires around.

Has anyone documented this process or have a link to someone who has? I will take lots of pictures when I do it for sure and post a FAQ thread, so .... the more help I can get the better it is for anyone else looking to do this swap.

- Do I need any special parts?
- Will I need to touch the fusebox?
- Should I buy a new wiring harness for the engine bay?
- Do I need to buy a new water temp sending unit?
- Oil sending unit?
- How did the stock oil pressure sending unit work and how was it wired?

Thanks!

Check GMCPauls web page. I think there is a wiring chart that tells you were to move the wires.

I used the info found there and it works great!!

Thanks, I got the information on where to move the wires from the FAQ page (it links to a site with this info, maybe it's GMCPauls, I forgot already).

I'm wondering about the other questions I asked and whether anyone has pics of the process.

GMC pauls write up is what I just used. I even found the 67 steel oil pressure line.
And a vaccum gauge from old Harold. I cut up the glass and put a AM tach in the middle. Bought a wood bezel of ebay and cut out the middle to fit around the wider
camaro column. Was alot of slow custom work and Alot of beer.

I'll be watching this post because I couldn't figure out GMCPauls directions.

Glad I'm not the only one

. I'm a visual person. It really helps to see pictures and ask questions for everything that people forget to tell you or don't explicitly say.

Re-wiring the loom is pretty easy once you figure out how to remove the wires with the metal connector intact. Once the individual wires are out (do this one at a time), you can just plug them into the loom in the correct spot.

I used a small allen key to depress the "catch" on the metal connector to release the wire.

I did the swap without any problems in one shot. This means it has to be easy.

Yes and when your done rewiring you'll have two wires left over to use for the new
Batt. gauge.
