Hi All,
I'm hoping someone can shed some light on an electrical question I have because I am a little confused. I have purchased a set of VF Series II bimodal mufflers and have successfully prototypes a control board to open and close the valves. Now it comes to wiring my control box to the car. At first I simply wanted to find out how the VF Series II was wired. I have all that info now. The only thing is that my VF Series I seems to have fuses and relay installed that relate to the series II bimodal exhaust.
So, First I found the schematic for the bimodal exhaust as shown here.
And the Rear Fuse box layout as shown here.
And what I found is that the 20A fuse F17 and the exhaust relay are both installed on my Series I.
I have tested to fuse and there is power running through it and the relay pins 86 and 87 have Battery power and chassis ground as per the schematic. I don't know yet if pin 85 runs off to the BCM yet and I'm assuming pin 30 goes nowhere.
Has anymore had any experience with the bimodal exhaust and its wiring, and maybe explain why my series I was the exhaust relay and fuse installed?
Regards,
John
BTW.
Now just so you know, my Series I is probably one of the last made before Holden switched over to series II. So much so that a Carfacts history check on my VIN says it is a Series II with a 6.2L, but it is not. The Engine is definitely an L77 with AFM. So maybe some of the wiring was already changed before Series II went into full production.
