High/low switch for engine braking

[electricks]

Wife called today while going down mount eagle and had her try both low and high engine braking. Low held very well but she said that high did not really do anything. We just purchased this Travel supreme with the K2 chassis and ISM500 engine.Any ideas what to look for?? Did notice this week a pink wire that was disconnected under the dash with a round sigle pin connector on each end but left it unhooked??
Thanks

HI Rick: If you look under the plate the switch is set into you will find 2or3 plugs that can recieve the switch. Travel supreme had a bad habit of using the handy one, not the one that is for a two stage engine brake. when you take the cover off you will find the are clearly marked. Spartan did there job on the harnesses. TS just did not read the lable on the plugs. Rich

No luck the connector only goes on one way and it was labeled correctley.Spartan is sending a crew down to replace the fan assembely system and then i guess i will have to take to a cummins dealer?????
Thanks
