Two LS newbie questions
(LS1 2000)
I bought a book, but that does not help much. LS1tech is superior!
I think this is previous owners oil temp sensor (slightly below middle of pic, big white cable to it), can I put an oil pressure sensor here? My Moroso 20140 oil pan prevents the previous sensor setup next to the filter on the stock pan.

Is there a tach signal somewhere here to be found? Are these the connectors to the Corvette instrument cluster? (The harness and ECU are already modified by previous owner)
Like said above, those all look like transmission plugs.
Trace the tach signal output from the ECM. I assume you have a 411 and I think its pin 10 on the red connector.

For the tach sensor, find a wiring diagram. I sliced in it to run the wire for my tach. Read up on what tach you have because some require a resistor because the pulses are different.
