T5 Plug & Play Conversion

Here's my DIY to convert your DI/APC to T5 plug & play style.

My car's a 91 9000 Turbo and the T5 harness is from a 95 9000 Turbo. I have yet to attach it to the motor, cause my pistons are out to get coated, so will have to update once it actually works.

I went this route of using plugs from other harnesses to make a harness which can be removed easily and can be adapted to another car with very minimal work. You can just use your existing plugs or just tap into whatever wire if you'd like. My way there are only three wires that I have to tap into (BCV GRN/RED --- Purge Valve YEL/RED --- Switched Ignition --- BRN/WHT)
they are covered inside. You can use your existing Speed Sensor since it is attached directly to the Instrument Cluster. You will need to get a CPS (Crankshaft Position Sensor) and you will have to install a Timing wheel. There are a few threads on this:

**I would strongly strongly suggest using the grey plug which connects to the T5 harness. It will make your job incredibly easy.**

From the list of wires coming from the Grey Plug, There are a few which I did not tap into:

#10 Blu/Wht - Diagnosis
#18 Wht - Engine Torque Limitation
#20 Grn/Wht - Can Bus (Small Plug)
#33 Wht - Brake Light Switch (might use this one, not sure yet)
#39 Grn/Wht - Cruise Control
#49 Grn/Red - A/C Out
#50 Grn/Wht - A/C In

If anything changes, I will update the thread.

MikeD helped me out on a few things, so big thanks bud.
I've spent many many hours and days studying all these diagrams and wiring. Now with this DIY you can probably have your car T5'ed within only a few hours. Enjoy

**Just use your existing speed sensor, cause 95+ use this type of plug**
