I am running the same tb was wondring if you knew what wire is which on that pig tail ? thanks bob

I don't have the original pigtail. You can find them by using an ohm meter. Try this

Two wires are +5 Vref signal and a sense line. There is a third wire going to ground. Assuming that you have a proper potentiometer TPS, then +5 Vref goes to one side of the pot, the other side goes to ground and the sensor line is hooked to the wiper.

To hook up your throttle position sensor (TPS), disconnect the TPS, and use a digital multi-meter. Switch it to measure resistance. The resistance between two of the connections will stay the same when the throttle is moved. Find those two - one will be the +5 Vref and the other a ground. The third is the sense wire to the MegaSquirt® controller. To figure out which wire is the +5 Vref and which is the ground, connect your meter to one of those two connections and the other to the TPS sense connection.

If you read a high resistance which gets lower as you open the throttle, then disconnected wire is the one which goes to ground, the other one which had the continuous resistance goes to the +5 Vref, and the remaining wire is the TPS sense wire.

Well, I am finally off of restrictions and the Doctors gave me the go ahead to weld again. I just have to be extra careful to keep and metal out of my eyes for the brain scans in November. I was able to get a couple of more bends added in.

Did some more fab on the header.

Oh come on don't stop now, more updates. Cool project.

A little bit of work done on the car, a lot of work done on me. After going back down to UCSF San Francisco and getting another angiogram done we found that I still had an AVM in my brain that was at a risk of bleeding. After 5 hours of surgery trying to get to it through my leg they decided that they would need to "go in" to cut it out. They cut me ear to ear in an upside down horseshoe shape over the top of my head, and cut out a 4"x4" section of skull. The doctors were able to go through the brain and find the blood vessels that needed to come out. After another angiogram the next day I finally got the "cured" status. 50 staples later I was laying in a bed recovering and ready to get home and start back on making life "normal" again. I've been recovering well and ready to get back on all of my projects that have been on hold. So back on to the Ghia.

Cut off the ends on the CB intakes and brought them up to 1 3/4". Also added some weld to where the ports need to be opened a little. Just need to port and clean everything back up.

So good to hear you are finally better and can be part of the group again! Those welds are looking pretty good too, guess they didn't cut to much out

That is great to hear! Hope all goes well with the healing.

Wow, thats quite the story on the surgery WW!
Very glad we got you back! You evenb described the recovery rather amusing I must admit

Walter

Your positivity and enthusiasm to carry on is an inspiration Mark.... Very glad to hear you are well and truly on the mend, and getting back into it.

All the best.

WOW, Glad to hear your OK.

Ok I gotta see how the rest of that plumbing is going to happen
I am getting ready to start a 1600 Turbo very shortly and it looks like yours is going to hide away very nicely
thats what I'm looking for
This is a great build though just cant wait to see it finished
Great paint by the way

Bump. How is your head doing?
Any project updates?

Hey Mark! Great to meet you on the salt this year! With your welding skills you might as well build a cage and go for the 150 mph club. Your engine will deffo get you into the 130 club and I'm going a different route next year at boneville so you'd be the first Air-Cooled VW into the 150 mph club. Great build and a sweet Ghia Boss.

I spent days, weeks, and months putting in all of this wiring for the fuel injection in the Karmann Ghia. It only took an hour or so to pull out. Bye bye EFI I'm sure we'll meet again some day.
