Pinto Engine Loom
 

Hi Guy's

Have just started fitting my wiring.

But i have a few problems.

One of my problem is.
My sierra donor was originally fitted with 1.8 cvh, at some point it had a 2l pinto fitted.
The cvh engine loom was hacked about to fit the pinto, i was wondering if anyone had a proper pinto engine loom they didn't need in exchange for beer tokens.

The next problem is i've lost all my pictures i took while disconnecting the electric from my donor :mad: , so remembering what went where is going to be a bit tricky:o .
So i will be posting up some pictures and asking what is meant to be attached to this and that.

A big thanks in advance for any help that i my get.:D

Terry

Most pintos where wired up quiet basic so should not be to hard to get it all sorted

Did you not go for a new loom come the end?

Hi Baz,

no didn't get one, but the way things are looking i my have to go that way.

the loom i've got, was from injection engine and it was hacked about quite badly.

Terry

What have you actualy got?

A sierra 2.0 Pinot (carb) model should be runnign an ESC-2 spark control, the 1.8 CVH will have had a ESC-Hybrid. Or is this a PRE-Sierra 2.0 running Points?

I'm running a, 2L Pinto with weber twin 40's with a electronic dizzy.

Terry

Who's dizzy? The ford one or an aftermarket one?

It's the ford one, will post up some pic's later tt.

You will need the ESC-2 module to go with it then, as well as the loom.

sorry about the delay in pic's,

is this ESC-2 you was on about TT,

carbs
Attachment 1443
dizzy
Attachment 1444
coil
Attachment 1445
coil wires, does it matter which way round they go on the coil.
Attachment 1446

Ahh, my mistake it runs basic TFI not ESC ( my poor memory ).

But yes that module is your ignition amp.

Green to -ve
black to +ve

does the dizzy have a 3 pin plug on the side? You will also need a vacuum feed from the carbs ( idealy a balanced feed from both with check valves ).

TT

Yes it has the 3 pin plug, i was wonder about vacuum pipe, this is going to sound a bit dopey, but whats a check valve look like and how do i get a balanced feed.

Is there any vacuum take off on the carbs ( I would expect them to have them ) and hopefully each carb will have a combined vac from each venturi.

A check valve is a one way have to prevent one carb from sucking from the other. Ford ones are usualy white and black things with a port at either side. So long as you have a feed from each carb and each carb has a one way valve you should be ok.

TT

I my have a problem then, as there aren't any take offs on the carbs.

Terry

er am i missing somthing if there was check valves (non return) on the vac line then the dizzy would either be sucked to full advance or would not advance at all? do you mean flame trap like you find on lots of ford carbs tt?

all you need terry is a thin vac line from any one of the manifold headers or behind throttle valve to the dizzy.
so the dizzy can react to manifold pressure

Good point, it would not release, I am just thinking that you need to make sure that you get vac from both carbs and don't want to be sucking from one to the other (although if balanced you should have similar draw on both).



There must be a vac takeoff somwhere...

TT

If you only draw from one header it will only see manifold pressure when that cylinder is on the intake stroke. You will get a pulsing effect on the dizzy and inconsistant timing advance. That is why you need to draw from all four headers.

If you connect all four into a small container, then connect that to the dizzy you will get a steady vacuum flow

never been an issue for any of the xflows,pintos, lotus twincam and one vauxhal 8v i have worked on with conventional dizzys and webber 40's or alike with vac advance.
the lotus engine was setup like it as a production car and i think thay knew what thay where doing.
only things that dont like seeing a single cyl vac is map sensors as far as i know
i dont expect a dizzy vac diaphram will react that quick
