I think it goes to the gauge but double check just in case.

Thanks. is there a diagram Showing where the "wires go" from the 3800 SIDE of 203 plug ? I'm only seeing F for MAF sensor, E for oil sender, J for injectors, and K for evap / trans / 02/ and boost. there's 11 more PINS, are they not used at all ? the stock "Fiero side" of 203 has a lot of wires hooked up. also, the fuel and AC RELAYS, ( there is only 1 wire mentioned that goes to the ac Relay). why does Sinister NOT have any of this in the wiring pin outs ??? I'm making a harness and have empty 203 and 500 plugs. I've made a harness 4 times before, every time I say "never going to do it again", but here I am. LOL Thanks

On the Sinister Performance website, go to 'Technical Info', then 'download wiring diagrams and pinouts'. The ninth item down is for the Fiero C-500 and C-203.

those gmtuners charts tell you WHAT the wires "DO", Not where they are connected to. and then ONLY for STOCK Fiero, NOT 3800 swap.
Spoon JUN 05, 08:09 PM
There are 6 references to C203 as to what wire goes where and 2 references to C500. What charts are you looking at?


Left side of chart: From 3800 and right side is To Fiero
