Question Welding..What to disconnect ???

HELLO...I'm new to this and I need some help...I have a 79 with a 5 speed I just brought home on Sunday...Everyone on these post's seems to know so much about 928's.I hope to be able to help someday too.. I need to weld a part of the chassis that is cracked..I read somewhere that you should disconnect the computer plugs before you weld .???..Can anyone tell me what to un plug so I don't ruin anything and where it is...THANKS A LOT.....Dave

It is just in front of the left front tire...It is a tubular part of the chassis it looks like it was tack welded...If I weld it will this damage ANY electronics..
Thanks.....Dave

It's always a good idea to unhook the battery before welding on these cars.

Some people would say just the computer. I would unhook/plug both!

Well your 79 like mine does not have a computer, but you should disconnect the battery so that it doesnt zap other electronics.

unless you're gas welding, the welder provides it's own ground. you can still fry stuff. i remember one guy said he thought he disconnected everthing but when the car was done his speedo was dead. he forgot to disconnect the transmission harness.

there's always something...
