Some friends and I just did this swap for a local guy... B20z clips wont plug into just any year LS ECU. Look for a 99,00 ECU! They are only slightly different P75 had 2 versions, and the 99,00 had the correct clip set for the B20z harness. Its such a very small difference.... but to save yourself a rewiring headache get the right one.
We didnt have the right one during the install... luckily AllData gave us the correct wiring diagram so we just replaced pins to make the older P75 work till we got the correct one. Only issue is the fuel is mapped very different. The car wants to keep pulling but the fuel cut is killing it!

Re: (addmotorsportskimball)
my question to the above is why use b20 harness? im running an ls harness on my b20.. everythin is perfect.... unless you want to run a knock sensor... then that harness wont work... then again that ecu doesnt read a knock sensor... so yeah... ls harness goes right in...
