Ive searched day after day looking for a write up for the universal speedo healer v4 install in a 99-00 ek. no luck,i know mark Lamond is the guy to talk to and has pin-out diagrams but hes not easy to get a hold of, and pin-outs of clusters dnt help with the speedo healer. really need your guys help with this.

 

i would suggest having someone your confident in to do this... it requires alota costumization. not only time. thats why i put doing this off for the time being i have a 96 del sol. i hear it takes alota work

 

i have it in and everything else works perfectly, gas is a little off. but only thing not working is the speedo. the healer harness only has 4 wire to it,

black- obviously ground
red - obviously +12v source
green ???
white ???
