are tachometres hard to install on first gen rx7s? (1985)

do you need to be like a pro to be able to do it.. or can anyone do it?

also getting a pro steering wheel.. easy or hard to install?

thanx guys

 

both are very easy to install

the tacho has about 4 wires
* one goes to the ingnition which is +12v
* one gets grounded
* one connects to the -ve on the trailing coil
* one gets connecting into a wire that powers a light in the dash

and the wheel
u need to buy a boss kit to be able to put it on

 

thanx very much..

 

could you run a autometer tach off these 4 wires?
