1G NLTS Wiring for a 90 (with chip)

[tsi1991awd]

I am wondering how the clutch wire is modified to run NLTS. I am having a chip made with a stutterbox and NLTS. I have a 1990 and I KNOW these are different for wiring than the 1991+ is.

I have read on ECMTuning's site that you cut both wires to the clutch switch and wire one of those wires to ground and one to pin 104 on the ECU harness. But I'm not sure if this is just for use with Link or if this is for use in general or what?

And what switch am I supposed to cut? I have heard there are two switches...one at the top and one at the bottom. Not sure which to cut or what.

Can I use straight wire? I have no cruise control or anything like that....I'm not sure what this "special wire" is that TMO and Keydiver at DSMChips talk about.

Any help would be appreciated.

Nobody knows? I know I can find out for the 91+ but nothing really specific on the 90.

Hey hows it going, I took a peek at the keydivers website as i have a 90 chipped ecu I am going to put in my 92.

89-94 Clutchwire Installation

The page states that is is for ALL 1Gs 89-94. Also the "clutchwire" is simply plain old wire (which i plan on making myself ) which in spliced between the green clutchwire and the ground pin on the ecu....Full instructions are included on the page. PM me and let me know how it goes!

What I did was cut the green wire at the clutch switch, extend the wire. Cut the wire from pin 104 at the ECU, and then splice the extended clutch wire into the harness side of 104. Left the black wire at the clutch switch alone.
