shingabiss Posted February 26 Share Posted February 26 I put a JDM 1zzfe engine in my 2005 base Matrix. There were a few differences between peripheral components; throttle body was cable type, exhaust manifold about 1" too short and a different knock sensor so swapped with old engine. Engine is in and most everything is hooked up except 2 'mystery connectors' coming from the wiring harnes on the end near throttle body. I cannot find any sensors ot other mating connectors. The clipped harness that came with the engine does not have these two connectors. I have examined both blocks/heads to search for differences, there arent any. This is Matrix Base. Below are the two connectors in question; top right and bottom center. Wracking my brain! Quote Link to comment Share on other sites More sharing options...
