I recently purchased an 08 gmc envoy denali with the v8 engine. After working out some issues that were going on, I realized that fuse box is the v6 fuse box. I am wondering if this is alright to keep under the hood. I noticed the v6 doesnt have as many fuses as the v8. Is this taking away any functions of the car? would it be better to find a v8 fuse box and switch back? Am I able to do any basic electrical additions(such as reverse light bar) without risking a malfunction in a different system? Any thoughts or comments would be appreciated.
