easy soulution. find the solonoid that this sensor opperates, bypass it with a piece of vacuum hose and be done with it. that way you'll have vacuum advance all of the time instead of just in 3 and 4 after it has fully warmed up. the reason why it was installed in the first place, is because most people don't regularly maintain thier vehicles and when they don't tailpipe emissions go way up. bypass it, keep it properly tuned, and get better performance in the long run.
that way you wopn't be spending a bunch of money for something that you don't really need.

it is possable, like someone else mentioned, that it's for an electric fan, but I doubt it unless it's a front wheel drive car.

it,s a coolant temp. sensor for emission controlls. you can probably live without it.

me thinks that she trapped him in his car and is trying out new possitions with him.
too bad, I need to chat with him.

answer the phone dummy!!!!!!!!!

figure out how much you can afford to spend on a real A series electronic distributor, including shipping, then let me know.

not really, it depends on how long you want to wait, least expensive is $20.00 and about 6 to 8 week wait. last I checked 1 to 2 week was under $50. overnight would cost about $100, and even that wouldn't get there overnight because of customs.
the one I sent to 1200 rallycar took 7 weeks on a slowboat and cost me $21.00

The conversion is a simple bolt in and a wiring modification.
there are lots of them here, I have 1 that is for sale/trade and can aquire more.
anyone wanting one needs to make an offer that will cover the cost of shipping and the time to go get them one along with the cost of the actual unit.
With it, I will include a copy of the factory manuel pages applicable to the dizzy and a wiring diagram, along with a parts list of factory part numbers. this is the real thing that everyone there seems to want, I'm willing to accomidate you if your willing to compensate me.
BTW, IF you have any questions about whether or not I'm serious, ask 1200rallycar dizzy pic

sorry, last time we traded words, it sounded as if you haden't made up your mind as to which way to go on that.
