# Wiring & Fixing ComfyUI-Manager

Practical pin-by-pin connection order and common error fixes for ComfyUI-Manager in ComfyUI workflows.

## Facts (2026-10-17)

- **Target Node:** ComfyUI-Manager
- **Required Inputs:** Top menu bar Manager button
- **Output Pins:** Install Custom Nodes, Install Missing Nodes, Model Manager
- **Package:** ltdrdata/ComfyUI-Manager

## Step-by-step pin wiring for ComfyUI-Manager

1. Drop [ComfyUI-Manager](https://comfy.ink/nodes/comfyui-manager) onto the canvas by double-clicking and searching its title.
2. Connect all required upstream wires (`Top menu bar Manager button`) from your checkpoint loader, prompt conditioning, or image preprocessor.
3. Route the output (`Install Custom Nodes, Install Missing Nodes, Model Manager`) into your downstream [KSampler](https://comfy.ink/nodes/ksampler) or [VAE Decode](https://comfy.ink/nodes/vae-decode-encode) node, then click **Queue Prompt**.

## Fixing dependency conflicts and type mismatches

If the console prints a Python import error or tensor shape mismatch on this node, verify that your checkpoint family (SD 1.5, SDXL, or Flux) matches any attached LoRA, ControlNet, or IPAdapter weight.

For custom node packs on Windows, run **Update All** inside [ComfyUI-Manager](https://comfy.ink/nodes/comfyui-manager) or grab a fresh desktop environment from [/download](https://comfy.ink/download).

## FAQ

### Why won't a wire snap onto ComfyUI-Manager?

ComfyUI enforces strict pin types. Check that the upstream output matches `Top menu bar Manager button` and insert a VAE Encode/Decode or preprocessor node if converting between pixels and latents.

### How do I bypass this node temporarily without deleting my wires?

Select the node on the canvas and press **Ctrl+B** (Bypass) or **Ctrl+M** (Mute) to test your graph without disconnecting cables.
