Another AAR Valve Question, Where does the red lead go? Options

[Craigers17]

Recently, I've been refurbishing the intake and FI system on the 914. I've noticed that a few of the valves are either inoperable or blocked off or both. The AAR valve red lead was not hooked up to anything. I'm trying to figure out where this lead plugs in? I've attached two pics...one of the valve and one of a a white wire that is pretty much the only thing near the AAR valve. So is this white wire the proper connection for the red AAR lead ? If not, where does the red lead go and what does the white wire connect to ?

I'm going to "PB Blast" this thing as well per some of the other posts, but any help on the connection is appreciated. Thanks!

The AAR lead definitely connects to a white wire. The only other connection like that on the wiring harness goes to the CHT, so if that connection is left over, that's definitely where it goes. Don't short that lead or you'll blow a fuse on the relay board and fuel pump won't run IIRC. In other words, there is a reason that connection is shielded like that.

Thanks Rob. You're gonna have to start charging me for technical support! (IMG:style_emoticons/default/beerchug.gif)

The CHT is accounted for and working, so this makes sense. 10-4 on not shorting it, ... while getting this fuel system sorted out, I usually keep the negative battery terminal disconnected anyway. The first time I cranked it after installing the new injectors, I actually had a fire extinguisher right next to the car just in case anything went south!

Thank goodness my consulting days are over (I hope). The only thing I still need to know about government consulting is that when the govt customer asks you how much money to implement the recommendations you say "We estimate one million dollars..." and wait to see if they fall out of their chair - if not, you quickly follow up with "...for phase one."

I'm sure there's something similar in the Porsche world.
