Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Omnitec dash control module etc - 2011 Plus 4

Well ! I've just about got rid of that contrived bit of kit dremt up by Omnitec. I've installed 4 hardwired switches to replace those on the Omnitec "mother board" for: the rear fog lamp, hazard lights, driving lamps, and heated screen.
I've installed a conventional hazard and direction indicator system using Durite flasher units, one for for hazards and one for the indicators, I may install one for the security alarm system i have in my car, although system has its own output for the flashing alarm indication.
The heated screen pulls about 5.5 / 6 amps and the switch was rated at 5 amp but being double pole i decided to use the 2 poles so it should be ok without a relay (keep it simple).
I've replaced that oddball logic LED warning light system more suitable LEDs from CBS, also got the switches from them, couldn't get the billet ali switches, out of stock, Chinese i suppose, but may change them when available if i don't take to these tidy little things that were available.
Ive got most of the warning lights working, hand brake, brake fluid, lights on, full beam, rear fog, left and right indicators, driving lamps, just need to battery/alt, and engine light working.
Decided on this little project when i appeared to have a faulty starter motor, which appears to growing arms and legs, battery was u/s, sulphate i guess, although i C-tekt it a couple of times, Halfords did change it under warrenty.
However it looks like I still have the starter motor issue, wasn't sure if it was dodgy connections/earths but I've connected jumper leads from the new fully charged battery direct to the starter and engine block and I still get either a labouring half a rev or a disengaged whirring....and of course the 2 bolts for removal are Loctited in according to my pal in the ford know.
Meanwhile I'm struggling with only wiring document i can find...the M.E.S harness layout! Im looking for info on the 3 relays, Start, Ignition and Fuel Pump, has any body got this info for 2011 plus 4, its actually the Plus 4 SS engine but I'm sure its the same on all cars of the vintage (?) Any info would be appreciated to save my poor multi meter working overtime.

Impressive work on replacing the Omnitec board

Regarding starter issue have you isolated possibility of the piggy back starter solenoid causing the problem, as this also activates pinion engagement?

Not sure what info you want but would imagine the relays are standard 30 amp 5 pin diode type albeit with centre 87a (n/c) contact unused in most cases.

Nice job with the Omnitech Dash Control Module.

That's on my to do list with my 2009 Roadster and I'm guessing it will have the same dash layout as yours.

Do you also have a Caerbont Dash Control Module in the ECU box in the engine compartment??

Indeed I do Bob, I spoke Caerbont last week to see if i could get any info, ive misplaced the gents name he was helpful as possible but didn't have much info on what it did, thought it just interfaced thier kit to the field devices which of course is more than feasible. The man with all the info in his head, Ian John, has retireď.

Was it Neil Meakin?

I spoke to him a few weeks back and he was helpful but needed to get more information.

Gently, gently, I think we might get more info from them.

On a regular +4 I believe those relays are driven from the ecu. Does your SS engined car use the regular ecu plus a piggy back ecu?

No Roger, my car has the Omex 600 series ECU as per the 4SS, I i believe it was a mule used in the development of the
SS, Omex did the SS engines and Richard Wragg owned the car a while, but i think you're correct about the relays as the +'ve side of the coils disappear into the engine harness.

No problem. I have the pinouts for the regular ecu but unfortunately it won’t help with the Omex 600.

Good luck

I might be barking up the wrong tree here but have you looked at all the installation and setup guide downloads on the Omex website.

When I swapped my 4/4 Zetec over to the OMEX 600, all the information including pins and wiring was on there.

The 3 relays I had were Ignition / Fuel injection, Fuel Pump and Engine Cooling Fan.

All the details are on the OMEX website.

You may have already seen all that of course.

Yes Bob, I think you may be correct there, ive dug out the vendor info on the Omex 600. I'm hoping that the issue is that ive disconnected a supply that goes via the ecu to the relay, tomorrow's job! Of course, I've another issue my starter motor appears to be "shot", its just whirring as mentioned so once I've got the pump power supply issue sorted i need the engine cranking in order for the pump to run, as you'll know from the Omex info. Big challenge is to get those 2 starter motor mounting bolts out in order to get the motor off. I've actually removed the plugs and tried to crank the engine on the starter and it won't have it whjch makes me feel its "shot", the battery is a brand new 720 Amp job, Roll on, its time to pump the 40DCOEs and fire up the crossflow 7😣
