Installing JB4 w/o heat gun... use a t-tap splice?

[StuOne19]

i recently purchased and started to install a JB4 on my N55 135i. after connecting the easy connections, I opened the ECU box and discovered that the two wires I needed to tap into were covered in plastic and would need a heat gun... which I don't have. i figured that I could use a t-tap splice for these two connections instead and gave it a shot.

the car starts no problem and still has a CEL from the catless downpipes but I'm unable to get the steering wheel controls to work. is my method a viable option or do I absolutely NEED a heat gun to take off the plastic and connect my taps that way? it's possible I didn't make a great connection also, so I'll give that a shot this afternoon as well

thanks in advance for your replies and advice =]

You can get a heat gun for 20$ on Amazon from Wagner, and it works great. Just buy one and do the install correctly per the instructions imo, we're not talking a lot of money.

It's too late to completely go back, but I would never use a tap for ECU wires so that you have to choice to completely revert to stock, and the tap is just yet another point of failure.

Take the fabric tape off and slide the plastic off. It's really not that hard.

That didn't seem like a bad plan except it seems like they all need to be plugged in and unfortunately my apartment's garage doesn't have any outlets available
