They usually just attach to the terminals on the coil.... didn't it come with a badly translated and poorly photocopied page of instructions?

Do a search. There are many threads that have covered this topic already.

don't know about your but mine was

red = ignition switched 12 volts

black = ground

white = 12 volts from your interior light i had mine going to ignition switched 12 volts tho

green = positive or possibly negative on the coil

 

hope that helps

Green is goes to the negative of the coil.

where is the ground wire?

 

and mine has an orange wire that goes to battery + where do i connect this up to

 

thanks for your help

[Valandor]

ground is either a black wire or find bare metal on the chassis to connect it to with a screw or bolt

Obviously did not take time to read the FAQ!

... maybe get it installed at a workshop.

 

or learn basic electronics, buy some tools and parts then

red = usually positive

black / ground = negative

white = usually lights

green = usually signal

pink = usually memory (not applicable for tacho)

 

you can spline into an existing power wire or run a new one from battery for power,

but

 

*you would want the device to turn off when you turn the car off*

 

so its best to splice into the accessories circuit or any circuit powered from accessories for low current

drawing devices, for larger devices use a relay setup triggered off accessories.

 

joining methods are:

strip plastic coating, solder, heatshrink.

cut wires, crimps, join crimps.

use wire taps.

use one way insert boxes.

use terminal strips.

use plugs, ie molex etc.

 

don't cut wires, then twist them together and cover with tape. its wrong in so may ways.

 

hey check this out:

how to connect wires

 

also a set of insulating rachet crimpers are far superior to those crap simple ones.
