If you are replacing your ride on mower engine with one of the new Briggs & Stratton Single Cylinder Ride on Mower Series Models, the wiring loom and connector might be slightly different to your old model, depending on what brand of ride on mower you have.
Your mower will have a starter motor engaging solenoid, so you must connect the wire that runs from this solenoid to the terminal on the starter motor. The terminal is located towards the base of the starter motor.
We have listed below, the wires found on the new Briggs & Stratton single cylinder engines and where they need to be connected to.
RED WIRE - This is your DC cable, it should be connected directly to positive power on your battery. This wire charges your battery.
BLACK WIRE - This is the engine kill switch, It needs to run to an ON/OFF switch and then run to earth. DO NOT CONNECT THIS WIRE TO POSITIVE POWER!
GREY WIRE - This needs to run to an on/off switch and then to positive power on your battery, this controls the carby solenoid for fuel.
ORANGE WIRE (IF FITTED) - Can be connected to headlights or any other accessories

I have a craftsman LT1000 riding mower and I replaced the engine with a Briggs & Stratton EX 1750. The new engine has two connections. A single red wire and a dual connector with a black and a gray wire. How do I make the connection to the chassis wire harness that has an Orange, Red, Blue, and Black pins? Is there a conversion harness for this application?
What happens if it’s wired wrong
