anybody have or know where i can get the stock 93 manual ecu pinout? i searched for a while and came up with nothing.

Ive been trying to hook up a thing to display my tps and injector duty cycle. I need the 0-5v tps wire.

Thanks, Mike

Seriously, you need to buy a shop manual. They're only about $80 brand new from Ray, and it's MUCH nicer to have a real paper copy, especially when you're dealing with wiring diagrams.

That said, section F of the shop manual has blow-by-blow ECU pinouts, what voltages you should be seeing on each pin, the whole nine yards.

with that being said, you probably want the full range signal with your device...which is PIN 3G

You shouldn't have any trouble displaying your TPS, but keep in mind there are two sensors, a narrow range and a wide range. You could display TPS voltage with a simple multimeter. But IIRC, the injector duty is sent as pulses across the wire, which you have to count to determine duty cycle, so it won't simply be a conversion of the incoming voltage to a percentage.

Here's the '93 wiring diagram:

I'm not hosting it forever, so get it while you can.
