Adding cruise control

[LittleOldSuzi]

I am trying to add cruise control to my Relay van. I know on the older vans the wiring is missing and it is a mission but I am lucky have the 6 pin connector by the indicator stalk ready for the cruise stalk. There are different cruise stalks versions I am told and on my van the 6 pin connector only has 2 pins connected (pins 1 & 6 - Yellow and Red). I understand that this is connected directly to the Body Control ECU but can anyone help with a part number.

We’ll need a VIN, and you may need other parts too.

I have messaged you the VIN, thanks.

I’ve replied. You need to post it here, not in a PM or I cannot see it.
