this one: S14 digital climate control install , but me and a buddy of mine had to swap a bunch of wires around... it was bad. the guy who wrote this claims that everything matches to the T but i beg to differ.. unless the 98 kouki's were totally different or something. i had caught a couple of wires he mislabled and he fixed it in the write up.

i'd hook it up the way the write up tells you to and see if it works right, b/c it's not uncommon for car makers to swap wire color mid-stream. btw, dont be scared of ripping it out, just make sure that you leave enough of a pig tail on the USDM plugs just in case you have to put it back in due to complication. and for god sake turn your key off when you're messing w/ the wires b/c i shorted my fan button on mine right after we had fixed it and now i have to order another.
