Converting 4 Pin Square to 5 Pin Flat OAT mod
I'm looking to replace my Outside Air Temp Module from a 4 pin square to a 5 pin Flat. Is this easily done? and does anyone have a step by step Procedure? I have 6 or 7 Screens that all have the flat setup..

This is easy.
4 pin square Pin# 1. black/red wire to power (+12V) 2. brown wire to ground 3. green wire to sensor 4. gray/blue wire to illumination 5 pin in-line Pin# 1. brown wire to ground 2. gray/blue wire to illumination 3. green wire to sensor 4. green/yellow wire to vehicle speed sensor 5. black/red or black/violet to power (+12V) There may be some color variations. The speed sensor freezes the reading in stop-and-go traffic, when road heat would otherwise cause the display to erroneously read too high.

Where would you tie into the speed sensor?
