Interesting about the speed sensor RSR, I've got mine connected but since putting in the lift I've damaged the speedo cable, thus no speedo now = no speed sensor. Now I've got codes, but reckon they were there before I broke the cable, just not "visable" at times when I'm driving.
Coming home from Mt Gambier where I last filled up I just broke 10L to the 100km to Bendigo tonight (27's

and 3.7 ratio diffs

). I'm keen to get these sensors sorted, just time and money
Cheers
