Can noid lights be used on an M62?

[Multibeemer]

I asked this same question in my rough-running-engine-post-valve-cover-replacement thread, but I thought I'd start a separate thread on this specific question to open the question to a broader audience: Has anyone ever used noid lights, or any similar technique, to troubleshoot whether the DME is sending a signal to the injectors? I'm getting an open injector circuit error code for cylinders 7 and 8 on my 03 4.4i. My concern is that noid lights are typically attached to one injector connector at a time, and the engine is started, running on one less injector than normal during the test. But since the injector connectors in the M62 V8 are all connected together via the injector control box, I don't know of any way to disconnect one at a time. So, when you crank the engine, it's going to try to run on just one bank of cylinders. So, can the noid light method still be used? If not, is there another way to test the DME signal to the injector connectors? Thanks.
