IMT / Iowa Mold Tooling Engine Function Module, P/N 70146433 (MTI 500622, Rev A). New old stock, 2022 build date, surplus from a shop cleanout. Never installed.
Fits IMT crane and mechanic-body chassis wiring, MY2011–present (EFM Manual #99905297). Also referenced in later manuals through MY2017.
What’s inside: six function relays plus a dedicated E-brake relay, a 15A ignition-power fuse, and a factory Weather-Pack pigtail harness — three 6-cavity, one 3-cavity male, one 3-cavity female, one 2-cavity, and one 1-cavity connector, all pre-terminated. LED status indicators on the case face for E-brake and Relays 1–6.
Pigtail terminations: the 14GA red (power) and black (ground) leads ship bare-ended from the factory for the installer to terminate at the battery/CJB. Those are not cut wires — that’s how the part is supplied.
No programming, no pairing, no matched components. This is a hardwired relay module — it drops in and works off the existing harness.
Sold untested. I have no crane body to bench it against, so I’m not claiming functional status. It is a passive relay box with no electronics to have failed, and continuity across the relay pins is verifiable with a meter in about five minutes.
Dealer list on this part is $469–519 and it is currently backordered at at least one IMT dealer.
Case is approx. 8” x 5” x 3” plus harness. Ships in a padded box.
