franco101 Posted January 16, 2010 Report Share Posted January 16, 2010 i am going with the sds em4-f distributerless system. I was wondering How will the rpm guage work if i am not using a distributor or coil anymore? how will i ge molehill to work. I don't know how many "F" series people there are, but I figured alot of people running edis systems are in the same boat. I assume that the wires to the coil are not to be used so how did you guys do it? Franco Link to comment Share on other sites More sharing options...

Franco Connect the green wire from your coil pack to this thingy:http://i25.photobucket.com/albums/c69/tarnug/Cars/th_DSCF0591.jpg Edited January 16, 2010 by Psykore Link to comment Share on other sites More sharing options...

Psykore Posted January 21, 2010 Report Share Posted January 21, 2010 Honestly I'm not really sure. They look very similar to the GM waste spark coil packs, but it's been a while since I've looked at them. Link to comment Share on other sites More sharing options...
franco101 Posted March 12, 2010 Author Report Share Posted March 12, 2010 Good thing I didn't throw away that thingy. lol. However that resistor is connected to the pos and negative terminals. Which side do I connect it to? Also the other resistor that was mounted to the other side of the coil. Do I keep it or remove it? Franco Link to comment Share on other sites More sharing options...

Franco franco, im not sure how your sds wires in. does it have a wire that is designated to go to the tach? if so then you would use the litle box mentioned earlier.it connects to the negative side of the coil, so im thinking it would connect to the negative side of your coil packs. however, if your wiringharness provides the wire to give output to the tach, you may or may not need that little box. as for the little black resister looking thingy. i dont think that is actually a resister, but rather a noise suppressor. this should not be nessecary. or at least its not nessecary with my ms system.

franco101 Posted March 13, 2010 Author Report Share Posted March 13, 2010 The sds coil packs does have a wire that goes to the tach. I will write what sds says in the manual: The SDS coil pack allows for two different tachometer output voltage settings, 200 volt or 12 volt. The voltage setting can be changed by moving a jumper switch inside the coil pack blue enclosure. You must remove several screws holdind the bottom lid to get access inside to the circuit to change the setting. The lid is silicone so it is difficult to remove.Check your factory wiring and locate the tachometers signal input wire. If this wire originally cannected to the ignition coil's negative terminal, then the 200 volt setting is usually required, typical of most 80's and 90's.If your tachometers wire goes into the factory ecu, then you should have the tach jumper set to the 12 volt setting. This is usually true on cars that have coil pack type ignition from the factory Autometer/Autogage tach's also work better with a 12 volt setting.

franco101 Posted March 16, 2010 Author Report Share Posted March 16, 2010 Connected everything up. Tach works and matches what programmer reads. Franco Link to comment Share on other sites More sharing options...
