Are 4.6l SOHC and DOHC engine harness the same?

Stealth sohc to dohc swap?

• i have a stealth from 1991, came with a sohc engine and tranny with the 2 and 4th gear syncros getting worn, had a new transmission from a 93+ that takes the larger axles size and is made to run like that, the engine was redone all the timing gaskets etc, and put back in, only has a small exhaust leak and a belt tensioner squeeks a little sometimes, but it still doesn't satisfy me, the cars fast but seems to hit its limit fast and looks way meaner and more powerful that it is, i wanna swap a dohc engine into it, and can afford to, but i dont know what all is need. - like for sure the alternator needs to be changed over, and probably a new wiring harness, but what else is different between them that id have to get in order for a swap to work, would i need a different exhaust or are the heading different and the pipe connecting to them the same, some help would be greatly appreciated, thanks
