Hi all, found this little gem of a forum after trolling the internet for some answers. Seems like a lot of smart people (smarter than me at least) here, so thought I would pick ya'll brains. A little background. I am installing a Painless (oxymoron) 10150 Direct Fit Harness to my California 1984 CJ7, plus installing a Howell TBI kit, with a MSD Street Fire CDI. There are some issues that need to be clarified to me, and may benefit others too. So I will expose my ineptness for the benefit for all. I will limit this to one pressing question for now. Per Howell instructions-"After the grounds are secured, route the labeled purple and orange wires to the starter solenoid on the right hand fender well or to the starter. These wires each have a lug that attaches to the stud on either side of the solenoid or starter. (FIGURE 11) The orange wire is battery power and connects on the battery side of the solenoid or the positive post of the starter. The purple wire connects on the opposite side of the solenoid or to the starter solenoid post of the starter. Connect the labeled white wire to the ignition coil negative terminal to pick up a tach signal. NOTE: Multiple spark discharge ignitions require a special tach filter to function correctly. Contact Howell Engine Developments if you need one." So the inept question time. I have a Multi spark ignition. I am attaching the Howell Orange and Purple wires to solenoid per instructions if that matters. However, should I purchase the special tach filter (as recommended by Howell) to connect the tach signal for the ECM from the CDI, or can I just connect the WHITE WIRE to the negative (-) terminal of the coil and be golden (or is that a bad idea)? If coil connection is ok, is there a benefit to connecting to the CDI over the coil? The only thing I can think of that may be an issue attaching to the coil is the 430 volts the MSD is sending to the coil and that being an issue! Kinda thinking the coil connection is a bad idea with this CDI (or any CDI). Thank you.......
I've read that drilling out the upper mounting hole will get my cps a hair closer to the flex plate BUT that is just close enough to improve the voltage to a much more respectable reading. My problem is, I haven't read anything that clarifies which hole. Am I drilling the mount hole on the bell housing or the one on the cps bracket. And this is my first post so I'll let y'all get the flaming out of your systems now with a second question. What in the wide wide world of sports are us early 2.5 (1987) TBI remix guys supposed to do when we need a MAT (NOT MAP) Sensor? NLA
