what do these to? is this for the fan...
these have been unpulged for as long as i can remmeber
what are they, what do they do?

 

where and what?
do these do? and what is #1?

 

and at last. the coil..... i now have a blaster 2 coil from MDS...
how does it hook up... do i need to ues a and b?

 

and also. lol i dont ask much do i?

i removed smog, the wires that whent to the box what do i do with them? do they send data to the ECM to know if theres a prob?

 

no body??

 

In the first post, one of those, the one that has the flat clip on connector, is for the temp gauge in the dash. Dont know what the other one is.

The stuff near the egr valve is the solenoid that regulates vacuum to the egr valve. One will lead to the manifold as teh source for vacuum and the other will lead to the egr.

As for teh coil, you need all of those. One wire supplies power, two are the solid state switched leads taht energize the coil, and the one with a connector in line on it is the tach. It would be possible to mutilate the wires and make it work with an older style coil, but the coil would have to be similar to the stock one in order not to overload the stock module. Easier and cleaner way would be to just get a good aftermarket coil and module thats ment for your car. Although its a waste of money as the stock stuff there now will be fine. The HEI system there will supply plenty of spark energy for your motor as long as everything is in good working order. Your money would be better spent elsewhere, like toward purchasing and working over a good set of 305 TPI heads or buying tuning equipment.

 

These are my observations:


Pic #1- One is for the O2 sensor (should be the round connector) and the other is for the coolant temp sending unit (should be square connector).

Pic #2- That is the EGR vacuum solenoid. There are two vacuum lines going from it and one goes to the EGR valve. The vacuum line you circled should go to the TBI unit (far left vacuum hook-up on TBI unit).

Pic #3- You need to use A and B if you got a replacement coil that has the same style and hook-ups as the old one. If you have an older one, I can't help you there.

 

If you wanted to use an aftermarket canister style old fasioned coil, youd connect '+' feed to module and +12 feed from ignition to the + terminal and tach lead and 'C' to the negative terminal. This is just from the schematics and Ive never tried it so youd be doing it at your own risk. It probably wouldnt produce any noticable performance gain over the stock one.

 

Another BIG performance tip: Ditch the bosch plugs...

Those 'fall-off' terminals really kill performance. After a while, the poor contact from the terminals being just finger tight will form oxides and stuff and it really blocks the spark energy. It got so bad that my motor wasnt even buring all the fuel. The spark was too weak to light it off properly and it ran **** poor, got 8 miles to the gallon and misfired, even with new wires, coil, and module. They carbon tracked my old wires and the arcing turned them into goo and silicon oxide dust. They fell apart as soon as I touched them. Also wasted my module and coil. Get AC Delcos or any other plug that doesnt have a terminal that screws on. With all the thermal cycling its impossible to make them stay tight no matter how much you torque them.

In so many words, theyre nothing more then a fancy german take on garbage.

 

they work, fine on my camaro

 

Trust me, get rid of them ASAP! Theyll be trouble down the road. Once the terminals loosen up, theyll cause arcing and excess resistance which will cause the car to run like crap.

 

Ah, knew I had one of these plugs still haninging around...

 

All the crap on the towel came out of the threads on the plug terminal. Since the boot seals it the only place it could have come from is from arcing creating junk on the threads because theyre only finger tight after a few thermal cycles. You need big, fat, loud sparks in order to jump the gap under high pressure in the CC and all that junk blocks the current flow. A weak spark = fuel not being burned...

 

To be honest with you, that white connector in your first pic looks like the lockup harness that goes to the 700R4 transmisson from the computer. It should be square with 4 plastic pegs only 3 of them should have wires goin to them.
