this has nothing to do with diagnostics or tuning, but i didnt know where else to post it....this weekend i'll be installing a dual gauge pod in my friend's 99 SS. hes got a digital tach and an air/fuel gauge and im going to wire each gauge directly to the PCM and tap into the O2 sensor and RPM tach signal wires. i just need to know which pin#s to tap into and maybe what color the wires are for verification.

so, if youve got a diagram, post it up, or if you know which pin#s these two wires need to go to, post that up for me please. thanks in advance!

Im curious, why are you gonna tap an A/F guage into the narrow band 02?

lol if youve ever seen the sweeping A/F gauges, none of em are accurate. all hes wanting is more or a light show (you can hate it or love it) so this will do just fine.

after visiting the link for the diagram, i cant find the pins im looking for. anyone with a 99 LS1 thats had to deal with the RPM signal wire and the O2 sensor wire please let me know which pins they are.

RPM = #10 Red Connector (white wire)

O2 Signal = #26 Blue Connector (tan wire)

All the pins/descriptions are there - #10 -WHT - Engine speed (tach) output signal, several 02 references?

for the a/f gauge use one of the kits from thunder http://www.thunderracing.com/catalog...vid=3&pcid=156
or just tap into the purple white wire on top of the drivers side fuel rail
