Welding on Tacoma's?

Hi all, I've been building Toyota's for the last 10 years or so, but this is my first Tacoma (2001 SR5 V6 Ex-Cab Auto Trans)

I'm getting set to weld up some sliders and weld them to the frame rails. Is there any inherent issues with welding on the Tacoma's that I should know about? Ie: Should I unhook any electrical stuff like the computer before I go a weldin'? I never unhooked anything on the older trucks and never had a problem, but this Taco has a lot more sophisticated computer stuff on it than any of my other junk. Just figured I'd check. Obviously, I'll have a good bare-metal ground close to where I'm welding on the truck.

Just have a good close ground and you should be good. Also, use frame scab plates in a diamond shape with the points knocked off to spread the load and reduce stress risers. Tacoma frames are somewhat thin.

just dis-connect the battery, it's cheap insurance. I wouldn't really worry about anything else.

Just ground correctly and burn away.

Utilize frame plates for sliders. They are not even 1/8" wall.

IF it were me i would just take the extra 10 minutes and disconnect the computer and battery. That way you know you don't have to worry.

I always disconnect ECU and ground on battery on every vehicle i weld on, including my Tacoma. Whether you need to, i don't really know. I do it for peace of mind. Can't hurt!

Make sure that there's nothing on the other side of that frame rail. There was a guy I worked with at Toyota that was modding his 1998 Tacoma and burned the thing up. He was welding rock sliders onto the frame rails and failed to notice that there were fuel lines running along the frame rail. He began welding on the rails and poof, the fuel lines ignited and by the time the fire was put out, the truck was gone.
