Just bought a Jacobs Pro-Street Ultra Team Ignition of craigslist for $75. Its brand new except it didnt come with installation instructions. Im just a little confused.

Im Using a TFI Dizzy, Theres the 6 wire plug "TFI PLUG" That plugs into the dizzy theres a, Blue, red/blue, red, Green and Black wire coming out of it.

The coil has a green and yellow wire coming out of a connector, The green goes to the green or blue on the tfi plug? Not sure where the other wire goes lol

The two red wires need constant 12v power. Either the green or Blue wire is the tach wire and im not sure on that because i have one diagram that says its the green wire and another that says its the blue wire, if its the green wire then what is the blue wire? Not used?


And for the two red wires... On my ignition control module i have a purple and orange wire, i believe those go to the red wires for constant power. But again im not sure because i dont have a diagram. If anyone can comfirm or correct me that would be awesome! Or if you have a Diagram can you pleeeassssee post pics ;D. Im getting really close to being able to start my engine for the first time.
 
Ok so i found out that i only need 3 wires off the TFI Connector."Ground" Black wire. "Tach, Green Wire". Constant power Closest red wire to green wire. So i wired the green wire from the control module plug to the green wire on the tfi, then the red one from the control module plug. There is an aditional wire on the red wire plug that i will run to the ignition. Correct me if im wrong. but other than that i dont need the orange and purple wires?
 
Ok so this is what i have gotten so far

So all i have to do is hook up the power and ground wire coming from the ignition control module to the BATTERY correct? Then i run the Green tach wire to my Tachometer. And run the yellow wire to the key ignition switch on the power on side? Then ground the black alarm wire from the ignition coil And plug in the tfi. Then wire up the starter. Is that it? Or did i do something wrong with my wiring? Sorry for all the questions and conformations, I have never done an ignition on a gasoline engine before. Especially without a diagram.

heres a couple pics of what i got going on...

Thanks for that ^. It helped clarify my wiring was correct.

Now on the driver side in the engine bay, theres like 7 or 8 Plugs coming from the firewall. Other than the one for that alternator and lights and stuff, what else will need to be wired? And what plug is for the ignition? Pics would be awesome! Thanks
