The 8920 will not produce the right signal needed to send to the ECU on a 77 280z with the magnetic pickup. The 8910 despite the advice from MSD and from search's on this forum WILL work if put inline with the coil wire from the MSD 6a. So red wire on the 8910 goes to the orange coil wire. White wire on the 8910 goes to the blue wire that runs to the ecu. If anyone has any questions about wiring a 77 280z up without using the transistor ignition AT ALL. Please let me know! I will do my best to help Josh+Andrew

Ok so we replaced the starter after basically killing it from all the testing. We then rewired the MSD based upon information on this forum and the directions from the MSD site. I am still confused it wont start unless the starter is engaged. So if the starter is engaged it works fine. Grr frustrating.

Ok, The wires that connect to the resistor by the coil are as follows: white\black from (or possibly black\white) + coil to resistor blue - coil to "junction post" on resistor black\white on far end of resistor up to ignition Black\blue center resistor to condensor black\blue center resistor to ignition. Are we connecting the two black\blue wires there? Also, what is the little condensor deal? Looks like it just goes to a ground, is it the little item that looks like the coil deal from a power inverter? Thanks for the help. Very much appreciated Andrew edit: , my brother postd on his computer before i could on mine. thanks again though

Thank you so much PM me your address if you want some coffee check our website pick one out. Josh

Hey, I'm Andrew....in case you couldnt tell from the username. Anyways, my brother and I picked up last august or so a ITS prepped 77 280z. Full cage, with bump out for door and all. Killer price. To and from Texas in under 2 days from illinois to pick up the car and countless extra parts (some of which might be for sale in the future ) Anyways, we got the car to race in ITS up here, and long story short. My brother got married a month or so after we got the car and had just started a new job. Yadda yadda yadda, Fast forward to now......We are back to putting in the finishing touches of the car to make it exactly how we want it. We needed to replace the fuel tank, so we fabbed up a nice trick tank box and got all that welded up and in. We also decided that the stock wiring\haggard setup that was going on up in the engine bay seemed like absolute death for reliability, so we opted to do away with that. You can see in our electrical thread that that is our major problem\struggle right now. . Much fun, but at 4am nothing seems to make sense. Anyway, here are some pics of me using the Z at a drift day. We're not intending to use it for that at all, but at the time, I didnt want to use (my now crashed....compliments of my dad) my turbo mr2. Was fun for it, and hottest car on the block there L28 > sr20 you can also see some pics of my cars that have replaced the mr2, and random other crap from when we painted the car (we werent thinking with the all black paint) more pics here: http://www.developer10.com/users/joshuagore/joshnandrewssuperalbum/index.php Looking forward to some fun racing if we can get around to it. And shameless plug for my brothers new Coffee company Simple Coffee, which we hope to help support the Z racing;). Good stuff www.simple-coffee.com Andrew

My brother and I an effort to simplify our 280z'z wiring have removed most of the stock ignition parts. We have replaced them with an MSD6a, 8920, Mallory coil, and the stock magnetic pickup that came on our 77 280z. We have the fuel injector pulse wire hooked up via the blue line. We have the smaller gauge red line from the MSD going to the ignition panel we are using. We have the smaller gauge red line from the 8920 going to the ignition panel we are using. We basically have the stock key in the ignition and it’s always on wired up and away. We use a master on off switch because it’s a race car so we do not have to have the key functioning in any way. Here is the problem the car will stay running if the ignition stays on. As soon as you kill the starter the car dies. What circuit don’t we have fulltime power too? Grr this is frustrating. I have the wiring diagram, and I have everything laid out in front of me. Thanks in advance for any help given to this subject.
