I think your gonna need to post some pics of whats going on.
http://www.veryuseful.com/mustang/tech/engine/images/mustangEngineHarness.gifThe Wiring Harness That Goes To The Injectors Has These Small Mini Boots That Go Onto These Studs That Screw Into The Original Manifold .there Is No Place To Install These Sensors (grounds Or Whatever They Are)
yes and yes it won't cause a problem if you put it into the intake ducting before the throttlebody .my bad i figured it out , these holes are the same thread, it is the act sensor that does not have a hole to go into in the new manifold.I heard you can relocate it into the air intake tube without any problems have any of you guys done that before??
