I have a 89 Toyota pick-up with the 22re. I bought this truck with no spark. I quickly found that there was no power at the coil. I checked the fuse it was good but there was no power there. So i jumped the the fuse to power and smoke came out from under the hood. I pulled it and when the smoke cleared i found two wires spliced together and grounded to the firewall. They were plugged into this plug

I unplugged it and rejumped the fuse and the truck started right up. But with out 12v supplied to the fuse i have no power at the coil. Can anyone tell me were i can get a good wire diagram or possibly give me a hint? Thanks
