Do it in the adapter harness... You may have to do some wiring in the main harness if the Maf is not supplied with sensor ground or power. I would have to look at the wiring diagram.
Brother thank you soo much but I fixed it! The lean condition with the a9l turned out to be fuel injectors. One of the rings at the top ( not o ring ) was broken(cracked) and I had another one with a chuckle missing on the ring on that one. Afr fixed itself! Thank you for the 411 in that , I’m not sure if I even wanna mess with it now lol
