thanks guys! think im on the right track now. trans is a 700r4, i have actually bought gears twice now, the aftermarket color/number of teeth don't seem to match gm stuff, may try again later to get the speedo working.

If I am hearing correctly: in my situation, installing a muncie m-21 behind an '86 TPI with factory wiring and computer, I can find and use the OE 86 yellow box, and cable from tranny to yellow box, plug the harness from yellow box into computer, and cable out of yellow box to my aftermarket mechanical gauge, and I should be okay. Obviously, I need (and have) the correct cable drive gear that matches the rear end gear ratio.
Is that correct?
Obviously, I will need to reprogram the computer for the manual tranny, and I have the code for that ('89).
I tried ordering the JTR generator, but they were out of stock and refunded my $$ after I waited several months.
Upon additional research and seeing the yellow box...the answer is, "if installing the OE Camaro speedo, yes use the yellow box. The speedo is mechanical, but has atached the pulse generator, which the yellow VSS buffer then plugs into. if installing aftermarket mechanical speedo, source the 2PRS unit from JTR. If installing an aftermarket electronic speedo, probably ok to use the OE tranny mounted VSS."
