Bosch 0 221 503 700 Coil terminals

[Lotus54]

I am fitting a  Bosch 0 221 503 700. Coil (no distributor) I got it from QED, but they do not answer me.

I am in the states, and having trouble finding spark plug wires. I am not familiar with the coil terminal type, and have had no luck finding info. I know off Opel Astra (not sold here) but while I can get wires for those, not likely will the be right length.

If anyone knows the terminal type name or other info I would greatly appreciate help


Thanks
Mark

Here's a link to the magnecor custom HT lead page. It may give you some ideas. I would have thought you could have got them custom made in the USA. I find the magnecor ones very good. I am using a Valeo coil pack which might be the same as yours.

I thought it would be easy- but I do not know the name of the coil terminal type- so do not know what to ask for.
I ordered some that I could cut to length, but have the wrong end.

Following that link showed some details that help.
Thank you

Edit:
I checked, there is a Magnacore USA.
So I will just order a set from them. The PDF has excellent instructions on ordering.

Thanks!

Contact Ivey Engines in Portland, OR. Colin or Cameron Ivey. They will have Taylor wires with whatever terminals you need. They build and tune Twincams. www.iveyengines.com

The other source is Omnitech Engineering in uptown Bellingham, also a Twincam builder in https://omnitech-engineering.com/category/home

Thanks for the ideas.
On a good day I can see Bellingham area and Portland is only about 5 hours away.

This is a very non-standard setup, but now that I am pretty sure I know the coil terminals.

Thank you

Sorry to resurrect an old thread,
But did you conclude that you needed M4 pin sockets for the coil end of the plug?
I was going to make my own.
I am using the same QED conversion - will see how it goes !!
Thanks

I ordered them from Magnacore. I will have to lookup exactly what I ordered. They did work just fine, although I think the rubber going onto the coil could have been slightly larger. But they have worked fine.

Edit: here is the order form. I ordered the spark plug ends as 90º. They work, but I think straight would have worked better, or taller 90º. They do sit down in the well out of the way.

BTW, do you want what I have so far for programming the DTAFast? What QED sent was way off.
Also- on mine, the wiring loom was done incorrectly, so the TPS did not work. I finally got the info from DTAFast and moved the pins so it works fine.

Did you get the leads made in the USA or did you have to source in England?

I would love what you have so far on tune.
I am probably a month away from getting that far!
Interesting comment on the TPS, I just installed a similar TPS on my XI to get input for my AIM system on throttle position and that worked, maybe a calibration issue?
QED are not the quickest responders, I will probably default to a telephone call.

Magnecor are in the UK apparently, and I also found a guy in Telford near to my brother who also makes these things up.

Thanks for the help.

Magnecore is in the States also (see above link).
I will download the latest programming I have and see if I can link it here.

You will need to remove one tooth on the crank pulley- I think I have a picture of the one I did. Exactly which one is not that important, but it must match what is programmed also.
DTA just made the loom incorrectly in my case- swapping two pins solved the issue. But it took me some time to figure why it did not work, I initially thought a defective TPS. But after DTA got back to me with how it should be wired- it was an easy fix. (I have the pin tools to remove them).

I think I have another thread on doing this- with more details. I will try to find that also.
I put the controller inside - behind the glove box mounted on the bulkhead. Coil on left side, near fusebox (left hand drive car)

Thanks, I noticed the magnecoreusa link after I wrote, apologies.
My email will send by PM
