Swap: Temp gauge
from landers page.
"You have to run 2 wires from the back of the alternator inside the cabin by the ecu. Compare your old NA wiring harness and trace the wires that used to be at the alternator back to the plug they ended at (one of the 2 large orange ones inside the car). These are black and white wires. Now compare these pin positions with the current harness. Cut (or remove and re-pin) whatever wires are presently there (theyre not doing anything important) and splice in your 2 newly run wires. Be sure to cut and insulate those old wires, so you're not backfeeding through some other circuit. This keeps all your idiot lights from staying on all the time (this is normally an indication of a failed alternator, and the car thinks it has failed because the wiring was missing).
You also have to run 1 wire about 6 inches. On your old NA harness, find the yellow/red temp sensor wire that went under the oil filter. Now find it's pinout position on the orange plug that was inside the car. Compare this to the turbo harness' plug. Now trace the same wire on the turbo harness in the car. Cut or re-pin that wire on the *engine side* of the turbo harness, and jumper it over to the wire that is in the pin position the old NA harness had the wire at. Be sure to cut this old wire and insulate it to prevent backfeeding through that circuit. Now your dash temperature gauge will work like stock."
I kinda get it. Does any one have a vert turbo swap that can take pictures under the dash and show me what wires need to be spliced.

how about just getting a aftermarket gauge? seems like it would be a whole lot easier, but then again I don't really understand what you just said. stock gauges aren't really that accurate anyways...

My cuz got an Autometer temp gauge and it was simple to install instead of all that mess that you want to go thru...
Three wires... Red (+) , Black (-), Green(Temp Sender)
You do have to make standard threads for the Autometer sending unit .. but that is a simple 10 min procedure.
And you are good to go...
