I recently installed the HKS VPC and Apex'i AFC combo into my car and I need to clear up some questions. The VPC came with the harness, in order to put in the AFC, I cut the YELLOW wire that went from the VPC and into the harness, then I put the AFC wires in between. Is that right, or was I supposed to cut the blue wire? Second, everytime I turn the steering wheel, my boost gauge shows vacuum going up towards -2 psi. Is that normal because the vacuum hoses are now tapped off to the same outlet? And will that affect my boost controller? Thanks for any replies.
