We need to link to a series of different installation wiring diagrams here. Some are already scattered all over wiki. If you have one, please add it here.
'''Discussion on
We cannot afford fully customized harness, but our partners' experience shows that it is possible to make 1 or 2 types of "fits all" harness that is very easy to apply for almost any install.
Write your ideas below.
Common characteristics
- relays
- fuel pump
- ...
- fuses
- ECM
- injector
- ignition
- proper GND, GND5
- proper flyback
- WBO2 connector
- ... ?
TypeF - already made a small batch
- Firewall connector
- injectors for 4 cyl
- injector-type AMP connectors for sensors : will be crimped by installer in future versions (since different type connectors exist)
We already got a small batch made in Hungary, EU at a plan making automotive harnesses. Work quality is very professional. Some recommended silicone or tefzel insulation wires instead of automotive PVC that was used in this batch (they use the same wires for Audi, VolksWagen and other manufacturers).
Available under [Loom connector category]
See http://www.vems.hu/files/Wiring/Harness/ for more pics.
Here is the schematic of the harness:
TypeV - planned. Tell us how you would like it. Your opinion counts !!!
- no firewall connector
- suitable for up to 8 cyl
- We should make 75% ready harness for standard. Everything should be wired out into a connector and the enduser must finish the last 25% of the harness.
- And i think, because of most of the installations are 4cyl engines, we should make a standard 25% harness end part for standard 4 cyl.
- I'll present schematics about my ideas soon.

We plan to push price under 199 EUR, but we must order higher quantity for that - which requires some planning and research. It does make installs easier and faster.
Needed Wiring Diagrams (note that all are explained, but schematics aint hurt)
- dummy (dwell controlled by GenBoard) ignition
- directly controlled wasted spark not via EDIS
- EdisIgnition (already explained to details).
Note that injection wiring is independent from ignition, so if you list 4 ignition types and 2 injection, it does not make sense to convolute them (make 2*4 drawing).
We do not want to promote batch injection (it only has disadvantages, many small ones that one can live with, but why?). Otherwise the wiring schematic for batch injection is trivial. Enough to show sequential wiring.

Could someone add a link to, or just say which, program used to create these wiring diagrams?
- I've used Corel Draw 11. Here is the link to my .cdr file so you can play with it [wiringV3.1].

FWIW here's my Toyota 4A-GE 20v loom
