-As many of you know, the '90 models have quite a number of little differences between the '91+ model years. One of these is cruise control switch functionality -- on '91+ cars the cruise control switch is a switch to ground, however on the '90 cars it is a switched 12v line.  This means that the clutch-cut wire which was included with your DSMLink ​package will not work on the cruise-control switch (it DOES work correctly if installed on the starter switch), and you will need to do a little more work if you want to use NLTS on a '90 DSM using the cruise switch (the one activated when your foot is completely off the pedal).+As many of you know, the '90 models have quite a number of little differences between the '91+ model years.

 +Note: The ECU diagram here [[https://​www.ecmtuning.com/​images/​forums/​1GECUPinout.pdf]] shows the wire into the ecu as black w/yellow, although at least one person has reported that their 90 talon has black wire with red dots instead.

-The simplest method on a '90 DSM is to cut the wires going to the cruise clutch switch and rewire them to match the more common 91+ configuration. ​ The ECU/DSMLink ​just wants to see a switch to ground on the ECU input. ​ So cut both wires going to the clutch switch. Then rewire one side to chassis ground and the other side to the ECU input. Check all this with a meter, of course, but once that's done, you should be set.  The one drawback to this method is that you will lose cruise control cut out with clutch pedal activation. ​ For most people, that's not a big deal because they either no longer have cruise installed or they don't use that particular feature anyway.+The simplest method on a '90 DSM is to cut the wires going to the cruise clutch switch and rewire them to match the more common 91+ configuration. ​ The ECU/ECMLink ​just wants to see a switch to ground on the ECU input. ​ So cut both wires going to the clutch switch.
