Hi. Hope u have an LX handset. you will need this to change functions with in the control card.

First of all you will need to change SV1, SV2,K1,K2, Operator Fan, back up bulb, if your truck is a freezer truck you will need to change RES1,2 and 3. Part numbers repectively for SV1 and 2 127269-002, K1- 062640-003,K2 - 062711-002, operator fan - 127259-006, back up bulb - 117994, RES1 thru 3 - 130117-002.

Now you have all the parts you will need to change some parameters in the traction card. Functions 2, 12, 14, and 15 will require adjustment.

Change function 2 from 125 to 90
Function 12 from 61 to 90
function 14 from 25 to 16
function 15 from 38 to 57

hope this helps.
