Please help ...getting code 0505 after Boost a pump install

[Devin 97 Blue GTS]

Guys,

I installed a boost pump and went for a **** drive every thing was OK until this mourning, started the Viper and the check engine soon came on. Code 0505 (idle air control circuit). I did not even touch this part of the Viper. All I did was cut the green w/ white and the black from the fuel pump module and C1 position 19 to activate the relay for the Boost a Pump.(I also connected a vacum hose to the boost pump from the manifold)

Have you reset the code to see if it comes back ? Also unplug and plug (maybe spray with electical cleaner) the IAC connector before you reset the code.
