changing distributor to magnetic pick up

My son has an 86 dodge GLH non turbo 2.2. All emissions and the computer have been removed and we added a MSD and new coil, but were told the MSD would not connect to the distributor unless it was converted to a magnetic pickup. I have the pickup with black, red, and aluminum wires coming from it.

My questions are; how do I connect those wires to the green and purple wires from the MSD, and how critical is the positioning of the magnetic pickup, should it be horizontal across from the rotor, and should it be adjustable to set timing?

My knowledge is limited on the internal working of the distributor.

Thanks for any help!

I have contacted MSD and they were not very helpful. I am pretty sure of what I need to do beween the MSD and the distributor. My issue is how to corectly modify the distributor to a magnetic pickup.

thank you for your help

Not sure how to spell it, it is a Hal Effect. It sits under the base of the cap and looks like (for lack of a better term) a space ship with a magnetized pickup and three wires, red, green, and black.

What was explained to me was the MSD would not recieve a signal from this type of pickup and it need to be converted.

A friend of mine got a magnetic pickup (3/8" diameter 1 1/2" long with black and red wires) from a chrysler race engine company that the guy said to build a bracket and drill a hole thru the side of the cap to line it up were the old pickup was.

THe missing details have me concerned as to how this is really going to work. My biggest concerns are proper location of pickup and loss of weatherability/driveability with a hole in the cap.

I think once I understand better the functionality of all the components within the distributor that will help.

Sounds like I have a real mess?

Sorry I took a while to get back. I keep forgeting to look into the advanced rodding section. The Hall effect sensor set up is far superior than a magnetic pickup because it gives a very stable and sharp signal at high RPM. The magnetic type's signal tends tp flatten out and eventually becomes unreadable at high RPM. Some MSD control units hook up to points ignition system where the points just give a grounded signal. The module that's connected to the Hall effect sensor does just that- grounds the coil to earth. Maybe u should send the unit back and get one that works for points and just connect the wire going to the coil negative to the MSD unit and connect the MSD unit to the coil. I'm curious to see how u go because I've just fitted a Hall effect sensor setup on my SBC - cost me $11 in used parts lol and works a treat.

You should be able to hook up a common ignition module to the hall sensor and then run the output of the module to the MSD. Then MSD to distributor. If you do a google for hall sensor ignition module, I bet you can come up with a part number. The Hall is much better and can definately be used in conjunction with an amplifier(ignition module).

thank you for all your help. I will try to locate an ignition module so I can use the Hall effect pickup.

Thank you again.
