AArrrghhhh! Just received an SLP manual fan switch. After hooking it up per the supplied instructions, it works great. Turns the fans on just like promised. The only problem(s) are that once connected, the ABS INOP, ASR OFF and AIR BAG warning lights are all illuminated and do not shut off. WTF gives? After disconnecting the SLP unit and reconnecting the factory harness, all is well again. Anyone else face this? Any suggestions?

 

Ouch...not to rain on your parade but you could have easily done that mod with a few feet of wire and a switch (grand total of maybe $2.00).
