Uses factory under hood fuse box and puts the PCM in the same location as the stock black box computer.

(custom PCM/ECM locations can be ordered)

All gauges work just like factory. 

Customer must ship the C/K harness and the LS harness from the engine there swapping.

If you don't have the LS harness I can add all new engine sensor and PCM connectors and wire.

If you choose a fan setup I will add fuses and relays to your stock OBS fuse box for them.

AC Ready: If you are unsure of your AC setup at the time of ordering or if you think you may want to add AC later. (See Picture)

Fan Ready: If you are unsure what fans you want to run (F-Body, NBS Truck, Aftermarket) order your harness fan ready. (See Picture)

4L80E Ready: If you currently have a 4L60E or an manual transmission and want to easily upgrade to a 4L80E (IF you have a manual you can upgrade to 4L60E or 4L80E) using my easy switch transmission key. (See Picture)
