Ignition Coil Wiring Diagram for the Connector not the Plug Wires

[Wanderor Cross]

Okay, so I wanted to find Ignition Coils that were easier to purchase in the US as most Esprit parts are harder to get your hands on.

The original Esprit V8 Coils are -- A918E6009F

I found these Land Rover Coils -- 48675 (2003 Land Rover Discovery 4.6L V8)

Visually they are very close, the coil numbers per tower match, the plug orientation is different but the same connector and they visually look the same when next to each other.

I got a set to test with as I think one of my coil packs is getting weak, but sadly the car doesn't run with them and I have confirmed I got the plug wires connected correctly.

I found this wiring diagram for the Land Rover Coils would any of you have a coil wiring diagram I could go over to confirm the pins are the same on the connector and don't need to be moved?

Otherwise, it is back to the drawing board for a good coil option in the US.

Would it help to cut the old one apart?

I'd have expected it to be easier to identify a donor part equivalent to the Lotus one given Lotus ownership at the time it was developed would hint at them coming from a GM parts bin.

Pin 2 is the common +V feed on the OE coil pack.

Have you measured the resistances of the different coils to see if they are similar?

It is hard to read but is the OE coil pack part number a Bosch 0 221 503 001? If so, that's a common coil pack fitted to several vehicles, e.g. the Vauxhall Omega.

These are the ones that I used.

The 'path of least resistance' is to order from one of the US Lotus Parts suppliers like JAE parts.

That's a great price, sadly though with me being in the US this is why I went looking for other options.

I could but the problem is I would like to not destroy the old ones since they work and currently these new ones do not.

I agree, but apparently finding a US version of the part has been the issue they were used on a few cars in the EU but not over here it seems.

I have never been a big fan of JAE, the prices are always higher than just ordering from SJ and paying shipping and the customer service as well as website leave me feeling like there is not much effort put into it.

When I can get coils from SJ for 68 each plus one shipping charge vs 100 each plus a shipping charge it's just not worth it. Sure they get here faster but clearly SJ is the better option and the customer service is excellent.

However they technically are a US option, so yes it's possible but I would like to find something a little more readily available then just one spot in the entire country.

I understand...but in their defense, JAE does hunt down and stock parts that are not available in the USA...and sometimes, they create parts of their own.

I didn't know that, good to know.

Honestly I think it's mainly just me knowing that I can't go get a simple part and have to keep a stock pile that bothers me. I hate not having spares of common parts that can be needed but then I also find myself looking more into the threads where guys have moved to Megasquirt I might just put some real thought into doing that in the next year along with moving to a digital cluster. Looks like it will help clear a lot of issues.

Just to finish this off, I tried switching coil connectors thinking I may have gotten the connectors backwards but the Land Rover Coils still did not work so most likely these cannot be used without repinning the connector or just no9t at all even though they seem so Similar.

However the suggestion of ordering from Trodo was great they were far faster and the price was great. Thank you again for introducing me to that, I owe you a drink @tmusc

If I get the chance to revisit the Land Rover option (Keeping the coils) I will see if I can figure out if it is a repinning or they just will not work ever.

Are you sure the problem is not elsewhere. I used those coils and no issues

The coils you recommended work fine, it's the Land Rover Coils I originally tried that do not work.
