I replaced my TGS  recently and I'm getting P1510  and P 2138  codes that when cleared come right back.  I also think that I'm in a power management mode...  lack of complete power...  there were 6 wires from the TGS  and a separate 2 wire black connector,  that on my old TGS  had no connector and was heat sinked to a dead end,  the wiring diagram from HD  does not show these 2 wires ... what are/were they for...  Also my cruise control will not work and I,ve trouble shot all these wires to the handlegrip set/resume etc all good  I think with these codes the ECM  will not let the cruise work  ANY HELP on this one....
