Just FYI if you are in Australia or New Zealand, Jaycar sell a suitable cap:

Looks like some cheap Chinese brand, but anyway.

I was under the impression that the stock wire harness had a cap already.

Does that mean an additional cap is just silly?

Probably wouldn't hurt. But who was it a few posts back said he built 7 sets with no cap and no issues.

Do you know if said capacitor is in the run of wire between the two coil plugs at the back of the engine, and the 4 pin plug at the front of the engine? This is on a non-VVT NB.

The reason I'm asking is that I'm looking at building a loom that plugs into that front connector.

I'm happy to pull an existing loom apart but if someone knows already it will save me a tonne of stuffing about.

Cheers

I've attached a pic of the plug I was talking about. Do you know if the capacitor is between this plug and the two coil plugs at the rear of the engine?

I'm actually a bit interested in this as well... seeing as I am building my whole harness from scratch, I'd like to pull the cap in the harness and use the OEM one.

I know the 90-93 does, It resides just above the ignitor and goes between ground and power on the blue wire from ignitor to ignition coil.

I've seen nothing that shows the 95+ does. The coils get power directly from the behind the engine fuse opposed to before it, directly off the ignition switch as the 90-93.

If I could acutally find the FSM in PDF format I'd buy them all, but I can only find these shitty Mitchell ones. But right now, I feel safe to say only the 90-93 has it.

The 01-05 certainly does have it (it is bolted on the back of the cylinder head), it is coming through a 6-way connector on the front of the engine (2 grounds, 2 wires for the coolant temp sensor and 2 wires for the capacitor).

I'll find it on my 95 harness today.

I dont see it in the 99-00 FSM. It shows 3 wires on the CLT connector...there's an extra V/W wire that I can't quite figure out where it goes.

Here's a retarded question. I have COP's installed and running on my car, and hacked my coil harness for the connector. Now I'd like to check my ignition timing, is there any way to do this? My timing light goes over the 1st spark plug wire, which now obviously is gone. Is my only route to borrow another harness and plug my old coils back in to do that?

The ghetto way I've seen it done is cut a spark plug wire in half. Put the spark plug end on the spark plug. Stick the other end in the COP and secure. Car should run.. and you can just place the timing light as usual.

Although I've heard good timing lights can still pick up the signal in the wires.

There might be a more sophisticated way. I've never actually done it, just seen it done with COPs.

Interesting. You're saying to just stick the severed end of the plug into the COP? I still have the old coil and plug wires which could be cut I suppose. I tried putting it just around the 3-4 wires going to the COP but didn't get any signal. Probably not the best timing light, though.
