ss badge placement

have just converted my vs clubby to manual and have a 355 stroker in it with a manual loom and computer from a vn ss . It has a high idle and I’ve found there is no signal or power to my iac valve. Probed at both the connector and pcm. Any idea what to check next ??? Or what powers those wires...

I need peoples opinions / help, Im getting this sticker made up by a local sign company but not sure where to place the SS emblem/cut out. The sticker runs from the front wheel arch to the edge of the back door. I was think roughly 8cm from the back door, what do you all think? Does anyone...
