EBC wiring using former MAF wires? Hunky-dory?
I'm adding DIY Autotune's EBC solenoid to my MS3'd '99/04 MSM project car and considering using the old MAF wiring for the EBC. It looks like I can reuse the existing switched-12v white/red for my 12v switched feed, and the light green/black for my MS3 connection, as it conveniently runs back to pin 2L on the old ECU plug where it would be a simple matter to cross connect it to my MS3 in the DIYBOB. Makes sense, right?
Anybody see any problems doing it this way? Thanks in advance- |
makes perfect sense and works just fine. I used a couple of wires from the diagnostics connector, but your solution is better stil.

Thanks-

The only thing to watch for is electrical noise. The EBC solenoid is a coil that gets hit with a high-frequency signal to open and close. This could cause a fair bit of noise on the line that might show up elsewhere if the wires aren't shielded.
I'd do it and then monitor the logs for noise. No noise and you're good. If you see a bunch of noise, you know what to do. |
Great idea, I haven't installed my DIYPNP yet. It works out well for you I may crack it back open and move the wires from the DB connector...
