PSI LS Wiring kit with Brain

[88Stanger]

Early 2000 5.3/4.8 (24X) Multec injector LS wiring harness with Brain from PSI
I also have adapters to go from Multec to next series injectors. The original harness was a Mass Air system and was converted (2-wire cut) to speed density. Could easily be converted back to Mass Air. Otherwise everything is there.
I removed it from my "69 with a 5.3 and 4L60E, basic stock rebuild with WS6Store Hot Cam. Ran fine, i just wanted to be able to see all the parameters while driving and bought a different system. Questions, please let me know.
Bought 2019, ran less than 100 miles due to surgery and illness and then I got a different system. Paid $1000.00 new, sell complete with brain for $500.00 OBO.
