This economical adapter harness allows you to reuse your existing ADEM2000 or ADEM3 engine control harness (ECM to firewall) when converting to a Caterpillar 40-pin ADEM2 engine. One end (70-pin) plugs directly into the ADEM2000/ADEM3 firewall connector, while the other connects seamlessly to the Cat 40-pin ADEM2 ECM. Ideal for mechanics and fleet owners performing cost-effective engine conversions.
