IMPORTANT: enter the case-INsensitive alphabetic (no numbers) code AND WRITE SOME SHORT summary of changes (below) if you are saving changes. (not required for previewing changes). Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: 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. '''It is very important to state your opinion ASAP, we're ordering a next batch.''' It's definitely a good idea to add a few spare wires for customizations, the original didn't have enough. Write your ideas below. '''Common characteristics''' * relays ** main power relay ** fuel pump *** the original had a small (easy to fix in 5 mins) error here, as the return input of the relay needs +12V (not GND as it was connected). Since the ECU pulls the output to GND ** ... * fuses ** ECM ** injector ** ignition *** not press receptacles into EC36-wire conn, so they can be applied (to chosen logic-level or power outputs) according to ECU options ** fuel pump ** wideband ** spare channel (fet) 1 e.g. iac pwm (external flyback diode) ** spare channel (fet) 2 e.g. boost (external flyback diode) * sensors ** iat ** clt ** tps * triggers ** primary (properly shielded cable usable as either vr or hall) ** secondary (properly shielded cable usable as either vr or hall) *** it might be reasonable to NOT press receptacles into ECxx, so these wires can be used for something else (knock, boost solenoid, whatever) when the secondary trigger is not used (most wasted spark applications). * proper GND, GND5 * proper flyback * WBO2 connector * serial connector close to ecm * ... ? '''TypeF''' - already made a small batch * F0: (only a very few pieces): ignition was 1+2 * F1: the ignition branch upgraded from 1+2 to 1+10 (max 5 is normally used for ignition. The rest is for extra functions) * F2: the WBO2 branches closer to the firewall connector ** that is 1 +12V (thicker wire, ~1.5mm2) and 10 wires that can be controlled from ECU. On the ECU side, they can be pressed into any EC36 position (to allow logiclevel or high current drive, or medium current). This allows any kind of customizations, boost, evaporator purge valve, ALS throttle kicker, more ignchannels, you name it * 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 aircraft grade wires instead of automotive. For now, they use the same wires as for Audi, VolksWagen and other manufacturers. Old harness only has 1+2 for ignition. http://www.vems.hu/files/Wiring/Harness/HarnessFull_0016.jpg Available under [http://shop.vems.hu/catalog/index.php?cPath=1_5 Loom connector category] See http://www.vems.hu/files/Wiring/Harness/ for more pics. '''The schematic the original version was made from :''' (note minor changes were applied, and the number of extra outputs were bumped up recently by +8) http://www.vems.hu/files/Fero/VEMS%204%20Cyl%20Wiring%20bovebb.jpg '''TypeV''' - strongly considered. Tell us how you would like it. Your opinion counts !!! * no firewall connector. This will have several advantages: ** more appropriate length, especially the length in the enginebay can be adjusted more freely ** lower weight ** lower cost ** the relay part (which is too big to be pulled through the firewall from the engine bay to the cabin, but only has 6 connections to the harness) will have a low pincount (but durable) connector ** no disadvantages: the harness can come out with the engine easily, just as it could with the firewall connector (only 3 connectorss disconnected in the cabin: EC18, EC36 and the relay 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. Make schematics about your ideas! ---- '''TypeX is available in WebShop, as [http://shop.vems.hu/catalog/index.php?cPath=1_5 Loom Connectr/bigharness]''' (additions to common), optimized for 4 cyl engines. TODO: export schematics in jpg/pdf * 4 injector channels (8 channel possible) * 1 + 10 wires at the "ignition" outputs, that is +12V and 10 wires that can be sticked to any Econoseal position, typically 2 wires (for 4 cyl wasted spark) + 8 extra control (BoostControl, staged injectors, NOS, whatever...). But any other assignment is possible, such as: ** 2..4 ignition channels (passive coils) ** 6..8 extra outputs (can be anything), example: *** 2 spare fet outputs (without flyback, use specfets for this, mount external flyback) *** 2 low power outputs (p259, e.g. tach, shiftlight) *** stepper out PDF schematics: * http://www.vems.hu/files/Wiring/BigHarness/pdf/ ** a HU=>EN dictionary added now (lame), we'll fix the color names in the .pcb files. Fire a query in webshop if you want the editable .pcb files (eg. because you want to change color names to English ). The editor has a free version (no export capability but print to pdf via pdf995) ** the extra wires are not included on this sch, they are in the ignition branch and let free on the ECU side (so can be fitted in any chosen econoseal pin/ 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. ---- [http://megasquirtavr.sourceforge.net/manual/Basics.Install.Mechanic.html [Manual: Basics.Install.Mechanic]] ---- '''Program to create wiring diagrams''' * Corel Draw 11 was used originally: [http://www.inet.hr/~artst/msavr/wiringV3.1.zip zipped .cdr file]. * a publically available program was used by the professional partner, I cannot remember it's name.
