Has anyone have a photo of the 1k resistor in a 424 computer I can only find a photo of a 808 computer

Ok so i am talking about when the engine is idling the gauge that comes with the spartan 2 kit is reading 12 afr when the spartan 2 is not connected when it is connected it pin d8 it is at 16.8 afr . Its a brand new spartan 2 controller kit i am thinking its now stuff i checked all the wiring to day...

Vs v8 auto commodore nvram spartan 2 controller. So install spartan 2 and gauge and it worked fine afr was 14.7 running good but when i connect the spartan 2 to the pcm 424 the afr went to 16.8 and now when i disconnected it goes to 12 afr now i don't know what happened any ideas what i have done.

Any knock boards left
