pinout questions

as a rough guide how long should the wires be to make up the loom as i am thinking of making it up a bit at a time then laying it out on the engine etc so i can find best route and and bunching of cables

Hi,
That's going to depend on where you're mounting your ECU and the furthest component away from it.
Having said that, ideally keep the wire runs as short as practically possible while still fitting the ECU somewhere sensible

where does everybody get their wire from also correct me if needed the wire needs to be 0.75-1.00mm but is there a amp rating that it needs to be

[Bat]

Hi,
You can use the 1mm for sensors and low current stuff, but you'll need something thicker for injectors, coils, etc...
The cross sectional area governs the current carrying capability of the wire

i have found someone on ebay that does wire in 10m lengths for about £2.50 so thats the wire sorted now i need info on the plugs
i am sure that i have read that the inlet air temp and coolant temp sensors use the same plugs as the injectors is this right if so where do i get them from
cheers

Hi,
There's 3 links in this post, you should be able to get anything you need between the 3 of them....

Yes most things have a 2 pin mini timer plug on them

cheers for the link
on the simtek link there is a junior timer and a junior power timer what is the difference

[Bat]

Hi,
The power timer is waterproofed with the white silicon sleeves and is releasable without tools.
The timer has a rubber boot that covers the back of the socket and needs a screwdriver to hook the metal clip out to release it.
Cheers,
Gavin

i was talking to one of the lads at work the other day about wiring and stuff and told him what i had in mind and he gave me a full engine wring loom from a e46 bmw that i have now taken apart so i now have a good few connections with a decent amount of wire and some wire with different connectors on
i am now thinking of getting the 36 pin plug with 2m of wire already attached and joining them together that way vems has all the wiring needed on the 36 pin plug should i ever change my set up
what does everybody think good or bad idea
also the ground wires what is better option twisted and soldered or crimped ring terminal

[gunni]

You don´t need to install all the wires, as you wanted neat?

You can install and remove the wires easily enough,
That makes it easier to add things to your setup later.

Sounds the perfect plan to me.

For grounds you twist and solder them together 10-15cm from the VEMS, then ground them with a crimped ring terminal at a suitable point.
