I bought an rs1800 injector loom for my zetec as I'm running the matching manifold and my mondeo one is past it. But I'm not sure if they're interchangeable as the mondeos injector loom doesn't include intake air temp sensor but the rs one does. The plugs are the same round 12 pin but I don't want to disturb the mondeo one to check as it's very temperamental. The loom is a 3 plug pre pats from an l reg mondeo. Cheers guys
