Does anyone have a copy of the wiring instructions for installing a Lindsey Racing Digital MAF? I took mine off my car and am helping a friend install it on his, but I've misplaced the installation info Lindsey sent, and would prefer not having to wait til monday to get them, we were really excited to do the car today. It's been so long I've forgotten which colors go to where on the stock harness...

Thanks!!

I should have it let me look around.

he just posted the link...also if you search the archives for "Mafterburner wiring", you'll find several good post on it there too.

It's not a Mafterburner, it's the previous Digital MAF (with the Power Perfect computer from Pro-M). I have the MAF and IAT sensors wired up, as that is the same as with the Mafterburner setup (it's the same Pro-M air-flow meter) what I need is to find where to wire the 5-wire harness off the Power Perfect (Black / Red / Yellow / Orange / Blue - i assume black/red are grnd/+12v).

Thanks!!

OY! upon reading that, i've thoroughly confused myself, unfortunately the original harness between the power perfect and the maf sensor is pretty much missing, it's totally my fault as when i cut it out of the old car i had integrated it with the stock engine harness so i simply cut it a foot from the MAF and IAT sensors and a couple of feet from the Power Perfect box and the O2/Duty gauge.

so i currently have the Pink, Black and Green off the 2 sensors going to the Yellow-Red wire of the old AFM plug, Yellow off the TEMP sensor to Green on the AFM plug, Yellow (there is/was no white as per the Mafterburner instructions) on the MAF sensor go the Green/Red (AFM), Red off the MAF will get hooked up to +12V (switched) last, so I'm left with a few questions......

I'm thinking I need to re-run a line to connect Yellow on the MAF sensor to Yellow on the Power Perfect, and then run a new line from either the Orange or Blue out of the Power Perfect back to the Green/Red on the AFM where I currently (mistakenly?) hooked up that Yellow line??? Is that the MAF -> P.Perf -> AFM routing, aka what it's intercepting and turning into a 0-5V signal for the DME? Right now I'm stumped as I know Red on the Power Perfect is also going to get a +12V (sw) and Black will be grounded, and it looks like Yellow out of the P.Perf should be reconnected with the Yellow on the MAF, but that leaves a question: What are Blue and Orange? I assume one is either a TPS or Coil wire off the DME/KLR for getting a reading to assist in calculating 'load' as displayed by the LEDs, and then does that mean that the other wire goes back to the stock AFM plug to then be seen as the (massaged) air-flow signal??

HELP!

Cliff Notes:

What are Orange and Blue on the plug coming out of the back of the Power Perfect computer (and does Yellow run from the new MAF sensor all the way straight, no Ts or splices or anything, to the P. Perf?)

Yellow on lindsey to Solid Green on old AFM harness
Orange on lindsey to Green/Red on old AFM harness
Black on lindsey to Yellow/Red on old Harness
Blue is nothing.

Just read the paper carefully take your time the answers will come.

BUMP for anyone who knows what wires are what coming out of the back of the Power Perfect.

that actually helps a lot, it looks like we have to run the yellow from the MAF sensor back to the power perfect, the orange from the power perfect back to the old AFM plug, the only one i'm unclear on now is what Blue on the power perfect goes to...

Hi,

I just have two questions... How much power can I expect from a lindsey MAF with Mafterburner on a stock car with stock chips ?

What parts have I to buy to install a MAF on a stock car (only the MAF meter and Mafterburner ???)?

thanks!

Blue is nothing goes nowhere
