Align the motor on the chassis (frame) and line up the
transmission and drive shaft. Take several measurements
and write them down. You need to build a small frame to
support the motor and it has to be aligned perfectly. Start at
the front pulley center line and work from there.
Your motor might have mounts, or it should and these you
can figure on using to mount the motor to the frame.
Remember not to take out all of the wires when you remove
the old gas engine as some of them will be used in the new
motor system.
Use a roll of tape and use it on every wire during the
removal process. You have to know which wire goes
where.
Control wires and dash mount wires come in bundles, so just
mark down where they go.
Make sure you mark the ignition wires, coil wires and starter
wire mainly.
Remember to save the speedometer wiring as it is digital
usually in newer cars.
You can, however remove the heavy ground wires because
much smaller wires can be used now.
When you are ready to install the on board 12 volt wiring
later you will be glad you did this step.
