Webtech isn't a joke. It's a great resource for all you need.
Don't even need a manual with it.
Maybe you just don't know how to use it.

could the ecu, also be called the engine control module. Thats all I found remotly close to an ecu on there, but hey i'll keep lookin later, but now its time 4 a ice cold beer. 8) , but hey dweet damn good idear.
webtech my friend, is not a joke at all, as long as its user is capable of operating it. wink.gif
pin #47 coming off the ecu. should be a white wire.

ecu is located where #12 points to in this pic...

you will probably have to calibrate the tachometer though, using dipswitches or something on the back of it.
think of that, i found all that info. above on webtech. wink.gif

im guessing red is power, black is ground, and with the last two one is the RPM signal and the other you'll have to attatch to some kind of "tach adapter" which is really just a resistor of some certain value.
