I have the ISSPRO trans temp gauge. I also have the replacement trans line with the fitting in it to mount it. I have the wire plugged into the probe, run under the oil pan and up to the firewall. But, there is not enough wire to run to my gauge. They sell an extension wire but if I don't need it, I would rather not buy it. How do you have your wire ran using the stock amount of wire?

 

I had more than enough wire to run inside cab,but if you don't just and as much as you need.Don't forget solder,heat shrink.Just my 2 cents

 

I got it. I ran it behind the head and then down to the fitting. THANKS!
