yes that converts it to the old style plug for 2008 model year make sure to clean the connectors slots with a trailer hitch cleaner tool dielectric grease (don't apply too much it may damage the connection)


don't forget to get a new gasket 29543727

Note: If ordering a control module for a 2008 or 2009 MY vehicle, also order connector p/ns 24259589 and 24259590.

Note: If ordering a pump for a 2008 or 2009 MY vehicle with the original control module, also order connector part number 24259588.

Note: If ordering a pump and control module for 2008 or 2009 MY vehicle, also order connector part number 24259590.

About this 24259590 Harness (note i'm not sure if this is the exact item)

8660d1fa738f6a5a49f3004df8635455.jpg

This part is a harness, automatic transmission wiring (external to trns-jmpr harness auxiliary pmp control module to vehicle harness), for Chevrolet Trucks, Cadillac Trucks, and GMC Trucks cars. It fits for 203 General Motors vehicles which were sold in the U.S. from 2008 to 2011. It's a genuine General Motors part with an OEM part number 24259590.


this connects your 2008 wires to the 2010-2013 power supply & new pump (if you replace the pump and control module)
