Hi im wiring a 1.6 pinto engine from scratch as im building a project car. It didnt come with any loom which is why ill have to wire it from engine to
lights etc.
I need help with the engine side of things for e.g. connecting the universal switch to the starter motor, coil and distributor.
Where will i need to put in relays and fuses .

If I was doing it again I would probably buy the CBS fuse and relay modial
The relays and fuses should be located in the passenger compartment to keep them dry and clean. A good place is above the footwell.
The pinto was often fitted with a ballast resister for the ignition so that during starting this resister was bypassed and full current fed to the
distributor and once the starter was disengaged current at a reduced voltage flowed to the distributor. If you leave this out and have the wrong coil
& capacitor fitted the breaker points will burn out very quickly. One way round this is of course to fit optical or magnetic electronic ignition
which I'd recommend anyway, it makes a huge improvement.
Between the ignition switch and the starter solenoid I'd put a 30amp relay to keep high currents away from the switch as it will last longer.
Basic diagram would be, but they have left out the relay above -
When building my 2.0 Pinto engined MK Indy I fitted all the fuses and relays under the scuttle, behind the dashboard. That way they're kept away
from engine heat and weather (rain). I used a black marker pen to write next to each one what it was for to help me if I needed to check, test or
replace any of them after the build process.

Premier Wiring do a good Sierra loom for not much money, all fuses etc, good instructions and help available.
All I would say if doing your own loom is build some slack in it as it's all to easy to make it that little bit too tight and a bother to fit. I think soft cloth is really the best cover rather than tape as it lets it flex.

Should add I used a Vicky Green wiring loom that was designed for a 7 type car with a Pinto engine.
Not expensive and money very well spent IMHO as it fitted the chassis perfectly and came with a large easy to follow instruction drawing.
If building another car I'd be very very inclined to buy a ready made wiring loom for the car to speed up and simplify the the wiring process.
I've got a pdf of the Sierra wiring diagrams if it's any use to you - PM me your email address if you want me to forward it on.
