Modding my V6

Hi, new here and from WA. I modify all my cars and have had my V6 Dark Label since 2018. Got a DPF delete and ECU remap from brand new along with catch can. I just fitted a wagner intercooler this weekend ready for a turbo upgrade.

Looking to install an EGT/Boost gauge before turbo install but struggling with EGT probe location due to the stainless heatshield straight off turbo and also getting accessory power and lighting power for dimming being the stereo and power outlets seem to have power permanently.

Hope someone can help
