Factory amp turn on wire for 93 bmw 740i

if you don`t want to weld it then you can try exhaust tape that you wrap around the hole and get the exhaust hot and it will harden. don`t know why you don`t want to weld it. or you can replace the exhaust component that is bad.

Check battery. Check solenoid. Check starter moter. Check wiring to battery, solenoid, starter.

That is a beautiful vehicle... and EASIER to work on
Than you would believe... IF you have the CORRECT
DOCUMENTATION...

Merely dropping the battery is not going to cause
the described IGNITION TROUBLES...!!

ALTHOUGH
the FACTORY manuals are a bit expensive
I highly recommend them...

Professional GRADE shop manuals ... then
BENTLEY Manuals.

Get your codes READ...

you EXACTLY what your car is upset about...

UNLESS it reports OXYGEN SENSORS...
If so... skip on over to plugged MUFFLERS &
collapsed CATALYTIC CONVERTERS.

Save your money...

the long block will, you will have to check wiring harness to see if electronic parts on engine need to be switched

How about tune up,wire,coils,fuel filter.

CHECK TO SEE WHAT COLOR WIRES ARE ON THE MOTOR TRACE THEM BACK TO SWITCH YOU SHOOD ONLY HAVE THREE MOTORS FORWARD & BACK /UP & DOWN FRONT / AND UP & DOWN REAR TRY TRACING THEM BACK TILL YOU ELIMINATE EVERY THING BUT TWO

clogged, fuse, resistor, bad fan,relay, in that order

My Advise is to REWIRE all SPEAKERS SEPERATLY & INDEPENDENT From Factory Wiring, as it is Safer to do this than to INCORPERATE Your Sterio Wiring into the Original Wiring, Some Vehicles Use Spicific Wiring to OTHER Components. I'm Sure this is NOT the Answer you WANT But I have Installed more than I can Countof Stereo Systems into Cars/Trucks ,Tractor trailers and Inicialy I Only Ran Into PROBLEMS When Incorperating into Factory Wiring Thus I Refined MY METHOD By Simply Wiring all EXEPT the BATTERY & IGNITION < Key ON Wires. ONE SLIP In INCORPERATING INTO FACTORY WIRING Can CAUSE SERIOUS PROBLEMS/DAMAGE the ELECTRICAL SYSTEM. I Realize that in MANY Vehicles this CAN and HAS Been DONE But at the Same time When you ISOLATE the NEW STEREO WIRING You KNOW EXACTLY what you Have. As Far as Color Codes they CAN and DO VARY from Year to Year and Makes Also. What I am Recomending May be SLIGHTLY more Expensive and Require Some Time BUT the End Result will be Well Worth it. Thank you for your time !

Are these questions ever answered ?????
