blake culp Posted December 27, 2005 Share Posted December 27, 2005 I have a 82zx that i swapped in a zxt motor and ecu. I am putting my megasquirt ecu in hopefully this weekend, can i use the stock dropping resistors or do i need to buy some from digi key? thanks for any info Blake Quote Link to comment Share on other sites More sharing options...
jkube Posted December 27, 2005 Share Posted December 27, 2005 Yes you can use the stock resistors. You will have to rewire them slightly because they are wired in together on one end, and for Megasquirt they have to be seperated out.

Tony D Posted December 28, 2005 Share Posted December 28, 2005 You will have to rewire them slightly because they are wired in together on one end, and for Megasquirt they have to be seperated out. They have a common power wire, with individual ballasted feeds to each injector. The grouping of the grounds need to be collected separately into two groups of three for INJ1 and INJ2. The power end of the equation is fine, you just move the grounds around for the Megasquirt Application. The spearation is on the ground side, not the power side---at least that's the way I think I wired mine up two years or more ago.... Quote Link to comment Share on other sites More sharing options...
blake culp Posted December 28, 2005 Author Share Posted December 28, 2005 Thanks Tony, makes perfect sense. Now as soon as i find them ill be in buisness they dont seem to be where my service manual says they are, interesting. Quote Link to comment Share on other sites More sharing options...
Tony D Posted December 29, 2005 Share Posted December 29, 2005 Over by the Brake Booster! I used a ballast from an 81 or 82 I believe. It was the only one I found that had a true SIX resistor pack, and not the more common 4+2 setup. The 4+2 setup has two plugs to it, and two power wires, but if you strip the wiring cover back far enough, you find the "two" power wores are spliced together to a common point that leads back to the relay. It's a small aluminum box attached to the sheetmetal with two screws. White plug on a short pigtail. It's there! See, I knew you would find it!

Gavin Posted December 29, 2005 Share Posted December 29, 2005 This is what you're looking for, under the drivers side flap-thingy. http://homepage.mac.com/gavinwilliams/resistors.jpg Quote Link to comment Share on other sites More sharing options...
Tony D Posted December 29, 2005 Share Posted December 29, 2005 Yep, that's the "4+2" configuration common from 75-80 or 81... Quote Link to comment Share on other sites More sharing options...
