HEI in Mopar ECU casing

HMMM, ok, so after i got it all up and running through the mopar wiring and plug and the module mounted and hidden inside the mopar box, i decided to go in the house to use the bathroom and think about why the spark is so weak..I come back out and she wont start! I pull the coil wire and no spark!! Damn, thought i burned up this module also, but its not! I took the first module, that i THOUGHT was burned up and rigged it all up like i did the first time when i brought it home from the junkyard and BOOM!, Big fat lightning bolt spark like in trailbeasts video! SO, the problem seems to be the length of wire. For some reason, if i run it through all that original mopar wiring, it aint got enough to fire it and the few times it did, it was a very weak yellow spark. Yes, this obviously makes no sense because trailbeast had some length to his wires also, but on my pig, it wont work. I dont understand it and it makes me mad after digging all the guts out of the mopar box and having the box painted up and fabricating an aluminum heatsink for it and all, really makes me mad. I guess now if i want to run the GM crap i will have to buy that little mount that guy sells that mounts the module right up under the distributor so the wiring doesnt have to be very far. Again that sucks because that mount he sells is for the 4 pin module and i have already bought 2 of the 8 pin modules. Just dont understand..
