I have just bought this http://www.ebay.com/itm/140906135095?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 not noticing its not the obd 2 plug n play. So I am wonder has anyone installed something like this in their's? or anyone have the obd 2 pin diagram stating which wire is which?

Well I figured out the wires I needed. Ended up useing the tach wire on the cluster and the vss wire behind the head unit. but now I need to figure out how to proofread or sync the hud to the cluster without driving and cause a wreck. Im thinking of useing jack stands on the rear end but scared of the safety issue if one drops eh. HELP!

Could possibly extend the wires and set the hud on the passenger side so you can calibrate it while someone else drives?

Could, but I already have everything in place and the wire where I want them!
