I'm looking at an aftermarket cruise control - something like the AP50.
Has anyone done this successfully without major hassles? - I presume the cable in the kit would have to connect directly to the injection pump??

Anyone fitted aftermarket cruise control to a GQ 4.2 Diesel?
I bought my '89 GQ shorty td42 with an aftermarket kit allready fitted. The cable connected straight to the injection pump as you stated.
The problem I had with it was, unless you were travelling on a flat section of h'way, the engine did not have enough power to stay in fifth gear with the cruise control controller controlling the fuel load. (lots of controls there). Ultimately I would have to go back to fourth by either flat changing or changing back and reseting the cruise control.
That was a pita and I eventually removed the unit.
Don't know much about systems available today but I wouldn't purchase one unless I had plenty of power. ie turbo

I have a turbo and it holds 5th on most highway grades (although EGT's will get up there if you really push it).
I have heard people say that CC with a turbo tends to cause the boost to spike more than normal because without cruise you tend to anticipate the hill and accelerate gradually before, thus reducing the need for a big boost spike.

yeah I got a ap50 fitted to my truck Great unit, straight forward install. Had the clutch switch fitted. ( A lot of people seem to dodge the clutch switch.) So far all good, What more can i say.
