Any HSW interface users in here? Iv run into a slight problem with wiring up my interface. I am running a 5 wire MAF on my 98 fbody because I'm using the TSP 100MM unit. Last time I was at the tuner the IAT temps were thru the roof so I installed a stock IAT and bypassed the one in the MAF to correct the issue. The grey and orange out of the MAF now are capped off, the instructions say to tap the gray from the interface into the tan wire on the stock harness. I'm assuming the orange can be left unhooked as it was the reference signal and that is being supplied by the stock harness. I can supply pictures if need be. Thanks

Maybe this will work better. Does anyone with a stock MAF that uses a Interface have a pic of the harness. That way I can build my own for a stock harness to a 5 wire MAf with a separate IAT sensor.
