Honda SL3 - How should I connect the 12+ Volt and the Ground for Without Data-link install?

Question

Hello,

I'm going to make the installation WITHOUT Data-Link as shown in pictured below.

 

How should I connect the 12+ Volt and the Ground?

 

A - The 12 Volt connected to the 12+Volt Cable in the ignition harness. 

**Ground already connected.

OR

**I've got an APS997E, that has a Ground Output While Running (-) 300mA wire, that would ground when activated.

With or Without a Fuse?

If using a Fuse how many Amp. 10 amp or how many amps?

Won't this drain my battery? if i.e. the car is let sit, say for a few hours/days.

 

B - Through a relay that gives Ground to the SL3 when activated.

I've got an APS997E, that has a Ground Output While Running (-) 300mA wire, that would ground the relay terminal 86 and Ground the SL3 Black (Ground) and Blue (While Running) wires. like picture below.

**The 12 Volt connected to the 12+Volt Cable in the ignition harness. With or without fuse.

**Won't this drain my battery? if i.e. the car is let sit, say for a few hours/days.

 

 

C - Through a relay that gives 12+Volts to the SL3 when activated.

**Ground already connected.

I've got an APS997E, that has a Ground Output While Running (-) 300mA wire, that would ground the relay terminal 86 and give 12+ Volt to the the SL3 Red(12+ or Positive) wire. like picture below.

 

Thanks for the help.

 

Nice Day.

 

Answer 1

The blue wire from the SL3 goes to the ground while running of your starter.

The red wire in the datalink goes to a constant 12V.

The black wire in the datalink cable goes to constant ground.

No need for a relay.
