Newer revision, but it looks like the same technology (ULN2455) now an obsolete part.
The philosophy of this circuit is that it is a comparator that funnels a bunch of outputs into a big "OR" circuit, such that any "true" condition that turns on the dash bulb out indicator lamp. I just found the headlamp inputs pins on the module followed them to the ULN part that measured them, and "snipped" the associated outputs (traces) from the ULN part. With these outputs no longer feeding the the big OR, they don't trip the dash light.
You need to get a pinout of the ICs on the board. It's actually hard to find, being obsolete and all.
Without having the part in my hand, I hazard not to guess at what to cut.
I have spare N7 module, I could mod and sell to you!
